Grendel sees every battlefield as a smorgasbord. His insatiable appetite rewards him with high survivability. Enemies will be eaten. And regurgitated.

Feasting on enemies like his own personal buffet, his hunger for battle is primal. This is Grendel, the devourer, the insatiable.

Dinner is best served with a side of mayhem. Bon appétit, Tenno.

Release Date: October 31st, 2019

Indulge amid the stench of battle as Grendel the voracious gourmand, greedily swallowing armies whole into his fathomless maw. Corpulent and courageous, he consumes prey to invigorate kindred warriors, or disgorges the eaten out drenched in putrid acidic bile. Stampede through strongholds as a spherical menace, leaving cadavers in the wake crushed by his thunderous quake. Grendel's feeding frenzy began in Update 26: The Old Blood.


Grendel's main blueprint can be purchased from the Market. Grendel's component blueprints are awarded by completing certain missions on Europa using Locators, which can be purchased from the Arbitration Honors vendor found in any Relay for 25 VitusEssence Vitus Essence each.

Purchasing a Locator will unlock the unique mission associated with it, which guarantees the associated Grendel component as a reward. These missions will have level 25-30 enemies, however players will be unable to use their Gear items, weapons with unique traits (e.g. Knell Knell's Death Knell) do not function (however, Syndicate Radial Effects from Syndicate Weapons do still occur), Kuva and Tenet weapons will not have their elemental damage bonus, Incarnon weapons will not transform and bonuses from Incarnon evolutions will not apply, Operators cannot be used, and any Focus abilities will be disabled. Also all Mods will be deactivated, except Warframe Augment Mods, which will still work. The effects of Archon Shards also will not apply. Syndicate Death Squads will also not appear in these missions. Arcanes do not work as well.

These missions do not have public matchmaking, requiring players to form pre-made squads.

Locators are only consumed after completing the mission, requiring the purchase of another Locator to unlock once again. However, only the squad host requires a Locator, allowing them to invite other players to participate in the mission, and the component reward will be granted to all players upon completion.

Lore & History

Karishh's Final Feast

Main article: Leverian#Grendel
View Grendel List
Grendel: Primal. Insatiable. And, as this exhibit will demonstrate, a creature of surprising compassion.

After the fall of the Orokin Empire, a surviving Orokin Executor - a violet-scented brute named Karishh - lorded over Europa's frozen, famine-struck city of Riddha.

Safe within his walled manse the moist and loathsome Karishh lived a lavish life while his frail citizens obeyed his every edict in the hope of receiving his pre-masticated table scraps. As the city starved beneath him, Karissh commanded yet another feast for himself and his gluttonous sycophants... twelve courses for each of his twelve grafted digestive sacs... and one... one uninvited guest.

Masseter Masseter:

There remains a shallow trench through the ruins. As if some colossal boulder had crashed from the manse and rolled down the hill... but what if it had rolled... up? Imagine if you will, Karishh's Dax on the day... peering out, dumbstruck by what they saw. They readied no blade, sounded no alarm as the expanding orb of gristle hurtled toward them. And then in a spasm of giblets, Grendel was before them. His 'cutlery' in hand.. the Masseter.

Sumbha Syandana:

Scraps of clothing matching Grendel's unexpectedly elegant Syandana were retrieved from the site, hooked on the remnants of gilded gates, stained with the evidence of his... degustation. Indeed, most of the Orokin hanger-ons who attended the feast... became it. And Karishh himself fled shrieking into the hills of Riddha, as fast as his twelve exo-sac levitators would carry him.

Ancient Allies:

It came as no surprise to me, to find this tiny fragment of Gauss just outside the city. Indeed, if one thing is for certain, wherever we find evidence of Grendel, we're sure to find some trace of Gauss as well. Did they breach the city as a pair? Or did Gauss hang back intercepting returning patrols, generously letting his friend Grendel eat his fill at the feast within?

Grendel Glutt Helmet:

Note the open-face, almost maw-like design. A fitting visage for one of such singular, rapacious predilections. Grendel may hunger, yes, but not with the excesses of gluttony. Not when others are in need. Oral history tells of Grendel, newly-engorged from his repast, rolling through the miserable slums of Riddha, reinvigorating the sick and the lame, the hungry and the dying, with the power he had stolen - consumed - from their oppressors.

Manse Gates:

Here we have shattered fragments of the manse wall and the gate mangled by Grendel's Masseter blade.

One can almost see, the city's masses, newly-rejuvenated by Grendel's healthful blessing, storming the manse. Shattered gates thrown wide, they take back what was theirs. Namely, control of their future.

See here the scattering of genuine Orokin dinnerware. Worn with time, these must have been used for countless meals as the people of Riddha bravely weathered the dark times ahead.

GrendelIcon272 Grendel:

Many Warframes have speed and litheness but power, momentum, impact... those require mass.

And there... the creased midsection - the seam. Does it split? Yawning with a jagged, vacuous aperture to... to who knows? A certain Orokin may have found out.

That night when the people of Riddha ate their fill, feasting until the frozen mountains lit warmly with the dawn. It was toward those roseate peaks that the Executor fled, pursued by Grendel. What his fate was I cannot say, but as the people feasted, so the story goes, they were suddenly struck by a strange, deep sound. A rumble carried from mountain to mountain: a Single. Satisfied. Belch.
After the Collapse of the Orokin Empire, Karishh found refuge within the frozen, famine-struck city of Riddha, located on Europa. There he would live a lavish life, consuming feast after feast while the emaciated citizens looked on.

The Warframes GrendelIcon272 Grendel and GaussIcon272 Gauss would then appear to liberate Riddha from Karishh's control. Gauss would remain near the entrance of the city, presumably intercepting any returning patrols, while Grendel would go on to plow straight into the city, consuming all of Karishh's sycophants and Dax soldiers. With his gut full, Grendel would then Nourish130xWhite Nourish all the afflicted masses of Riddha with the power he consumed, leading them to join him in storming the Karishh's manse.

Smashing open the gates with his Masseter Masseter, Grendel would lead the newly reinvigorated citizens, interrupting yet another of Karishh's feasts. The Executor would then flee to the far-off mountains of Riddha, pursued by Grendel. As the citizens sat feasting, Grendel would have a feast of his own, consuming Karishh in one bite.


  • When Grendel wields his signature Masseter Masseter, he will become immune to crowd-control effects while performing Heavy Attacks.
  • Grendel sports the third highest base health of all Warframes, behind InarosIcon272 Inaros and InarosPrimeIcon272 Inaros Prime.
  • Sprint Speed mods do not appear to affect the speed of Pulverize130xWhite Pulverize, however, the Mod TT 20px Motus Signal does increase double jump height whilst in the ability.
  • Despite retaining the UI of the last equipped weapon, Grendel is unable to activate Syndicate Radial Effects while in Pulverize.
  • Grendel is able to consume many of the specters in the junctions between planets, largely trivializing each encounter.


  • Grendel is named for the villainous giant in the epic poem Beowulf. Among Grendel's epithets is "the destroyer and devourer of our human kind," and he is described as eating the flesh from the humans he kills.
    • During his development, Grendel was referred to as the "Oni" Warframe. In Japanese folklore, Oni are depicted as hulking, horned ogres with a penchant for terrorizing humans, up to and including devouring them.
  • Several of Grendel's idle animations as well as the pose he strikes during Nourish130xWhite Nourish are modeled after Sumo wrestlers.
  • Grendel's alternate helmet "Glutt" derived from the word glutton, as a reference to his insatiable hunger.
    • This naming choice is a bit of a contradiction, as the Grendel's Leverian exhibit explicitly states "Grendel may hunger, yes, but not with the excesses of gluttony."
  • Grendel is the 42nd Warframe to be released (excluding Primed and Umbra variants).
  • Grendel is the first Warframe whose component blueprints are obtained from exclusive mission nodes, which requires Vitus Essences and, in turn, Arbitrations.
  • Grendel was originally intended to release simultaneously with his best friend GaussIcon272 Gauss, but required more time for development. As a nod to their friendship, Gauss appears in Grendel's Warframe Profile to receive his support from Nourish130xWhite Nourish, as well as a mention in Grendel's Leverian exhibit. Grendel also appears in Gauss's profile video riding a K-Drive while Gauss sprints beside him.
  • Grendel's belly maw snaps open with the use of his abilities, namely Feast130xWhite Feast and Regurgitate130xWhite Regurgitate.
  • Grendel's belly visually enlarges and gains jiggle physics when enemies are eaten and stored with Feast.
  • Voicelines spoken by enemies inside Grendel's gut have a muffled and gurgled sound overlay.

Primal. Insatiable. Grendel Prime devours all who oppose him.

We are losing this war, you say. You whisper that my Warframes are too genteel. Very well. Away with chivalry. Let us have monsters.

The law of club and belly, hunger and smoke. Beasts of cave and glut. I spread for you a cannibal feast. A toast, to the valor of mere appetite! You tremble! But the drool is on your chins.

For you birthed him, in all his innocent obscenity. This... is what you ordered. Grendel.

Devouring his prey whole, GrendelIcon272 Grendel slowly digests the enemies he swallows via Feast130xWhite Feast. Each enemy still alive in Grendel's belly passively grants him 250 Armor, to a maximum of 1,250 bonus armor at the 5 enemy cap.

  • Passive bonus value is displayed above Grendel's ability icons.
  • Mod TT 20px Gourmand provides an additional 150 armor bonus per enemy at max rank to Grendel's passive, increasing the armor bonus to 400 per enemy and the total armor bonus to 2,000 at enemy cap.
  • Armor bonus is added after armor mods such as Mod TT 20px Steel Fiber. For example, Grendel with a rank 10 Steel Fiber and one enemy alive in his belly will have Total armor = (350 × (1 + 1.1)) + 250 = 985
  • Armor bonus adds or subtracts depending on the number of enemies currently residing in Grendel's stomach.

  • Fixed a script error caused by Grendel’s Feast ability.

Update 35.5 (2024-03-27)

Nourish Helminth Change

Nourish is by far the most used Helminth ability, so we felt it was necessary to reduce its effectiveness slightly for the Helminth version only. Our goal is to remove situations where it feels like “You’re playing wrong if you’re not using Nourish”, without making the ability unusable.

Nourish when Infused via Helminth now has the following alterations:

  • Base Energy Multiplier has been reduced from 2x to 1.6x.
  • Base Viral Damage Buff has been reduced from 75% to 45%.

Everything else related to Nourish through the Helminth remains unchanged.

  • Fixed enemies in Grendel’s gut instantly dying if he jumps off a cliff with them inside. Now they will respawn safely on the ledge they were thrown off of.
  • Fixed Grendel stumbling at the end of Pulverize if he runs out of energy but still has enemies in his stomach. He should not be stumbling when he has a full belly!
  • Fixed a crash in Grendel’s Locators missions on Europa.

  • Fixed casting Grendel’s Feast on the Dax Equitem in Duviri causing the Dax to disappear off his Kaithe, rendering the fight impossible to complete.

Update 35.0 (2023-12-13)

  • Increased the Starting Energy of the following Prime Warframes so that they have higher Energy Capacity compared to their base version:
    • Grendel Prime from 100 to 115

Base vs Final Stats in Modding - Health / Energy / Shield / Armor Stat Overhaul

If you’ve spent any time invested in the deeper nuances of Modding, you may be familiar with “Warframe Math” - math that upon first glance doesn’t really make sense, but once you learn the inner workings of the game, it all comes together. While we can appreciate the value that complex systems offer to a certain subsect of players, there are other aspects of the game that should have clear and understandable outcomes. Namely: Shield, Health, Energy, and Armor Modding.

Pop quiz: what is 300 + 440%? If you answered 740, you may just be an Excalibur player.

Vitality (+440% Heath), Redirection (+440% Shields), Flow (+150% Energy), and Steel Fiber (+110% Armor) come with large modifier values that don’t seem to match their outcome in-game. This is because these Mods apply their multiplier to the base stats of the Warframe - i.e., the stats you have at Rank 0. In the Excalibur example, a Rank 30 Excalibur’s Health stat of 300 earns an additional 440 Health from max rank Vitality (+440% Heath) since it applies to his base rank Health stat of 100, resulting in 740 total health.

In this update, we have removed this obfuscation by having Health, Shield, Energy, and Armor Mods apply to the stats of Warframes at their current rank. Continuing our Excalibur example, instead of Vitality always applying to Excalibur’s base rank 100 Health, it would apply to his Health stat based on his rank - namely, the stat you can actually see in your Arsenal. If your Excalibur were Rank 30, his Health stat would be 300, which means Vitality’s multiplier would be calculated off of 300.

With previous Health and Mod values, additional adjustments are needed to make this revision work while maintaining game balance. By only changing where the multiplier applies, a Rank 30 Excalibur would receive an extra 1,320 Health from max rank Vitality, resulting in a total health stat of 1,600. This outcome is a significant buff, which is not the intention of this system change.

To remedy this, we approached this problem in two ways:

1 - We reduced the overall multiplier for Health, Shield, Energy, and Armor Mods.
Since these now affect Max Rank Warframe stats, these Mods need to scale differently to maintain the status quo. Additionally, we wanted these new values to be as clear and understandable to all players as possible! Here are a few examples of these value changes:

  • Vitality: Reduced from +440% to +100% Health
  • Redirection: Reduced from +440% to +100% Shield Capacity
  • Steel Fiber: Reduced from +110% to +100% Armor
  • Flow: Reduced from +150% to +100% Energy Max

Note: These are not all of the Mods affected by this change. We share the comprehensive list further down in this section of the update notes.

Doing some quick math, this means that a Rank 30 Excalibur (300 Health) with a reworked Vitality Mod (+100% Health, applied to the final Health stat) would receive 300 extra Health, for a total of 600. That, in contrast, is a nerf, which we also don’t want to do.

So, our next step:

2 - We adjusted Warframe Health, Shield, Energy, and Armor values to keep the end result of the revised Mods as close to the original values as possible.

With this change, Excalibur’s Rank 30 Health stat is 370. With +100% Health from a max Vitality Mod, his resulting Health stat would be 740, which matches what it was originally.

While this path to the same result may seem a little complicated, the outcome matches our intention: we want players to be able to look at their Health, Shield, and Armor Mods, and be able to understand how they affect the stats they see in their Arsenal.

In addition to everything above, we also increased the base stat values for Warframes so that these revised Mods offer similar value for lower-ranked Frames. To do so, we reduced the amount of Health/Shield/Energy that Warframes earn per rank in half, and transferred the sum of that value to their base stats.

For Armor, this is the one stat that does not increase with your Warframe’s level (with some exceptions). Armor values across the board have been slightly increased to compensate for the Mod changes.

Not to beat a dead Kaithe, but Mods will now be applying to the Max Rank stat instead of the Base Rank. You may look at these numbers and think “nerf” or “buff” depending, but the outcome is that total Modded values are the same, if not a little higher in some cases.

Warframe Stat Changes:

GRENDEL Health: Base Rank - 1095 (from 350) / Max Rank - 1295 (from 1050) Shields: Base Rank - 95 (from 25) / Max Rank - 95 (from 75) Armor: Base Rank - 370 (from 350) Energy: Base Rank - 175 (from 150) / Max Rank - 225 (from 225)

While there may be significant changes to Warframe Stats and Mod values as a part of this overhaul, the end result is that your Builds should mostly stay the same. The key difference is the added clarity of what your Health / Shield / Energy / Armor Mods do in your Upgrade screens!

Hotfix 33.6.1 (2023-07-31)

  • Fixed Grendel’s Feast not functioning correctly for Clients, resulting in the inability to use Nourish or Regurgitate, amongst other issues.

Hotfix 33.0.11 (2023-05-24)

  • Fixed Client experiencing staggered mobility and movement interruptions after using Grendel’s Feast on Dax Arcus as they are casting an ability.
  • Fixed Grendel’s Regurgitate slowing enemies with Overguard.
    • Enemies with Overguard are intended to be immune to slow effects. However, if Overguard is cleared while Regurgitate’s slow is active, then it will apply to the target for the remaining duration.

Update 33.0 (2023-04-26)

Hotfix 32.3.3 (2023-02-17)

  • Fixed script error with Grendel’s Pulverize ability.

Update 32.2 (2022-11-30)


Grendel is in new form with this update, and not just in his usual Pulverized rotundness. The following changes are intended to make his kit far more comprehensible and dynamic. We revisited the nuances of his abilities and their synergies, simplified them, and made them more situationally viable across the board. Overall, Grendel’s rework has given him more ways to feast on, fight, and flatten anyone that stands in his way!

Upon login, an inbox message will greet you with 1 x Built Forma for you to experiment and have fun with the Grendel changes.


  • Increased Armor gained from each enemy alive in Grendel’s Gut from 50 to 250.


  • Added a new HUD indicator to show the number of enemies and their Health in Grendel’s Gut. The Armor that he gains from enemies thanks to his passive is now also visible here.
  • Removed the 1.5/s Energy drain while enemies are in Grendel’s Gut.
  • Replaced the Armor Reduction with 2% of their total Shields and Health overtime (does not scale).
    • Health and Shields are more universally applicable, making Nourish affect enemies across a wider range of types.
  • Unified Radius for all ranks (25m for all).
  • Enemy auras are now disabled while inside Grendel’s Gut.
    • For example, after clearing an Ancient Healer Eximus’ Overguard, casting Feast on it will nullify its damage reduction buff while inside Grendel’s Gut.
  • Grendel can now cast Feast on enemies that are open to a Mercy kill.
  • Sentient enemies caught in Grendel’s Gut with Feast are no longer automatically expelled after 8 seconds.
  • Grendel can now Feast a maximum of 5 enemies at a time.
    • With the above buffs to Feast, the previous 40 enemy max would understandably be far too overpowered. The new cap allows players to make the most of Feast’s more powerful state and keep them actively seeking enemies to chomp on without clearing the whole map in one go.

Gourmand Augment Mod Change:
Was: Instead of Energy, consumes 200 Health on cast and 30 Health drain.
Now: Instead of Energy, consumes 200 Health on cast. Gourmand grants an additional 150 Armor (up to 400) per enemy.


  • Removed the “cycle to select + hold to cast” feature for Nourish’s buffs. Now, Nourish grants the following buffs to Grendel and allies within range on a single cast (with some exceptions).
    • (Previously holding to cast) Nourish’s healing effects no longer scales with enemy Health, but instead now heals Grendel 1000 Health on each cast.
    • (Previously Nourished Energy) Grendel and buffed allies are granted 2x Energy from Orbs (scales with Ability Strength Mods).
    • (Previously Nourished Armor) Grendel and buffed allies explode radial Viral damage (2 second cooldown, independent for each player) when enemies attack Grendel in a 12m radius (at max rank).  100% Viral Status and staggers enemies.
    • (Previously Nourished Strike) Grendel and allies are granted Viral damage to their weapons.
  • Added a “Gut Empty” error when attempting to cast Nourish without any enemies in Grendel’s Gut.
    • For Helminth versions of this ability, other Warframes will still be able to use Nourish without the consumed enemies requirement.
  • Nourish Helminth Ability Changes:
    • Prior to this update, the Nourished Energy buff was omitted when injected on other Warframes. Now, the new 2x Energy from Orbs buff applies.
    • The healing effects are not transferred over when injected on other Warframes and the Viral damage is limited to one stack.

'Hearty Nourishment Augment Mod Change:
Was: Clear status and gain 2s of Status Immunity for each victim in Grendel’s stomach.
Now: Clear status and gain 5s of Status Immunity for each victim in Grendel’s stomach.


  • Moved to the 3rd ability slot.
    • We felt Pulverize didn’t suit the “ultimate” status we’ve prescribed for other Warframes. So instead, we buffed Regurgitate to bring it up to the level we expect for a 4th ability slot.
  • Grendel no longer needs to have enemies in his Gut to cast Pulverize.
    • Worth noting that even if there are enemies in his Gut, there is no longer an energy-per-second drain tied to them as per the changes made to Feast.
  • Reduced the drain on an empty Gut from 10 Energy/s to 3 Energy/s.
  • Feast, Nourish, and Regurgitate can now be cast while in Pulverize.
  • Added a 50% Armor Reduction (at max rank) to enemies struck by Pulverize (scales with Ability Strength Mods).
  • Removed the Enemy Level multiplier from the total Impact Damage scaling.
    • ''New formula:  Total Impact Damage = [Impact Base Damage + (Number of Enemies Stored≤10 × 350)] × (1 + Ability Strength)''
  • Grendel will now heal 200 Health/s for 5 seconds after Pulverize is cast, and then decay to half its starting value over the next 5 seconds (scales with Ability Strength Mods).
  • Pulverize can now strike tileset breakables (crates, resource deposits, etc.).
  • Made several movement improvements:
    • Improved general control over Pulverize’s movement.
    • Improved movement went traversing slopes to make it smoother.
    • Momentum is now maintained on cast in and out.
    • Stairs can now be climbed while in Pulverize.
    • Sprint can now be used to go faster but at the cost of control over movement.
  • Grendel’s Pulverize form now takes on player customized colors and Voidshell Material Structure customizations if you own the Grendel Voidshell Skin.

Catapult Augment Mod Change:
Was: Launch Grendel in your aim direction. Costs 10 Energy.
Now: Launch Grendel in your aim direction. Costs 5 Energy. Crouch to slow down.


  • Moved to the 4th ability slot.
  • Added guaranteed Toxin Status Effect.
  • Added 75% Armor Reduction on Regurgitated enemies (scalable with Ability Strength Mods).
  • Increased Toxin Radius Range from 5m to 6m (at max rank).
    • Added VFX on cast to show the affected radius.
  • Enemies hit by Regurgitated foes are now slowed by 80%, which decays to 0% over time (6 seconds).
  • Changed the total Toxin Damage multiplier from enemy level to total enemy Health %.
  • Added a 50 Energy cost on cast.
  • Added a “Gut Empty” error when attempting to cast Regurgitate without any enemies in Grendel’s Gut.

Grendel Fixes:

  • Fixed Grendel losing all momentum in Regurgitate when jumping with no forward movement input.

Update 32.0 (2022-09-07)

  • Fixed the Granum Void target being enabled in the Grendel Locator missions.

Update 31.6 (2022-06-09)

  • Made the following changes to the Grendel Locator missions:
    • Lowered the Enemy level in the Grendel Locator Missions from 40-45 to 25-30.
      • This change was made thanks to Community feedback on the difficulty of the Eximus units in the Grendel missions after their rework, but it was also decided to lower the enemy levels overall as these missions were deemed too difficult.
    • Reduced the length of the Grendel Chassis Locator Defense mission from 15 waves to 10 waves. As reported here: https://www.reddit.com/r/Warframe/comments/uigpd9/grendel_missions_impossible_now_with_eximus_rework/i7fk209/
      • The changes to Eximus units in the Angels of the Zariman update made this particular mission much longer compared to the rest because you are required to clear all the Eximus at the end of every wave. Even with the changes we’ve made to Overguard in this update, we have reduced the waves to compensate for the added difficulty/time we found Eximus units continued to bring to the mission.
    • Syndicate Death Squads will no longer spawn in the Grendel Locator missions.

Update 31.5 (2022-04-27)

  • Changed Grendel’s Nian Skin icon to match the positioning of the other Grendel skins.
  • Fixed sprint (when toggle sprint is enabled) getting canceled after using the following Warframe abilities:
    • Grendel’s Pulverize

  • Made several armor placement adjustments for the Grendel Nian skin.

Hotfix 31.1.1 (2022-02-09)

  • Fixed crashes and excessive performance hitches when Grendel consumed an exorbitant amount of enemies and proceeded to vomit them out (90+ enemies). In the name of performance, we’ve added a limit of 40 enemies that can be eaten by Grendel at any given time, and spread out the vomiting of large numbers of enemies.
    • Test Cluster crash report/fix.
    • This was noted in the Update 31.1.0 notes but didn’t actually make the build.

Update 31.1 (2022-02-09)

  • Augment: Feast - Mod TT 20px Gourmand
  • Added a new Grendel ability tip:
    • "Feast's damage-over-time on vomited enemies, damage on Regurgitated enemies, and Nourish’s self heal on cast all scale based on the level of enemies Grendel devours."
  • Fixed crashes and excessive performance hitches when Grendel consumed an exorbitant amount of enemies and proceeded to vomit them out (90+ enemies). In the name of performance, we’ve added a limit of 40 enemies that can be eaten by Grendel at any given time, and spread out the vomiting of large numbers of enemies.
  • Fixed being unable to cycle Grendel’s Nourish options if you don't have Energy to cast it.
  • Fixed a script error when casting Grendel’s Feast ability.

Update 30.2 (2021-05-12)

Update 27.4 (2020-05-01)

Hotfix 27.3.14 (2020-04-15)

Hotfix 27.3.8 (2020-04-02)

  • Fixed Grendel buff wheels showing up when the ability has not been unlocked yet. Also fixed the buffs being greyed out until you leveled up enough.

Update 27.3 (2020-03-24)

Grendel Changes:
  • Grendel’s Nourish now mimic’s Titania’s Tribute buff selector.
    • If you’re unfamiliar with Titania’s Tribute buff selector, this means that Nourish is a tap to cycle/select buff and hold to cast. This is a reverse of how it functioned prior to this Update.
  • When consumed by Grendel, Sentients now have a max duration they can be consumed before popping out that is affected by diminishing returns.
    • This change was made to prevent Grendel from prog stopping missions where all Sentients must be exterminated for the mission to succeed.
  • Grendel can now consume Grenades - cause why not!

Hotfix 27.1.2 (2020-02-18)

Hotfix 26.0.5 (2019-11-06)

  • Grendel Changes & Fixes:
    • Grendel can now cast Nourish while Pulverize is active - to which we’ve added a new sound!
    • Grendel Feast expel deals increased damage based on the number and level of enemies. Also deals the same damage as a radial AoE.
    • Grendel Regurgitate damage radius increased from 3/3/3/3 to 3/4/5/5 and increased damage scaling.
    • Grendel Pulverize no longer ends when he runs out of consumed targets, instead it starts draining Energy like Ember’s Immolation.
    • Grendel also gets extra acceleration for Pulverize if he uses Nourish during it.
    • Added sound to when Grendel stumbles due to running out of Energy.
    • Fixed Grendel having fast legs after using Pulverize

Update 26.0 (2019-10-31)

  • Introduced.
