Hydroid summons the power of the ocean depths. He provides crowd control with aqueous attacks. His enemies will meet a watery demise.

This is Hydroid, a deadly marauder from the deep.

Whether the seas or the stars, Tenno, Hydroid takes a foreboding command of the battlefield.

Release Date: April 10th, 2014

Wash ashore with oceanic momentum to turn the tides of war. Below unfathomable depths lurking in an abyssal trench, the Kraken awaits his call. Drench the surface dwellers in torrential downpour and deluge as the Maritime Marauder, Hydroid, sails across strange seas to pillage and plunder. Command elemental water to rend foes asunder, as horrid tendrils grasp flailing prey and relentless waves erode away the drowned.


Hydroid's main blueprint can be purchased from the Market. Hydroid's component blueprints can be obtained from defeating from Councilor Vay Hek on Oro, Earth. The mission requires Mastery Rank 5 to enter.

  • Hydroid is derived from the Greek "Hydro"  meaning Water and the suffix "-oid"  meaning 'Of similar form to', likely alluding to his ability to transform into water. It is also a life stage for species of the Hydrozoa class of jellyfish.
  • Hydroid was claimed by the Development Team to have been inspired from the theme of pirates and seems to resemble Davy Jones from The Pirates of the Caribbean movie franchise.
  • Hydroid is the first Warframe to use self-degrading Argon Crystal for construction in the Foundry.
  • Hydroid is one of the few Warframes that has visible "eye-spots" on his helmet.
  • Hydroid is one of two Warframes with powers capable of ignoring enemy armor, the other being AshIcon272 Ash's BladeStorm130xWhite Blade Storm.
    • Hydroid was the first Warframe to have DmgTrueSmall64 True Damage, followed by Ash's revamped Blade Storm. Hydroid's True Damage also ignores shields.

Command the ocean's fury with this king of gold and silver. Featuring altered mod polarities for greater customization.

Fear... is the greatest of faith. While our immortal vines have left us distant from our baser selves, consider our subjects:

Those who gaze upon our cloud-swept towers, with simmering, violent envy, they hold still the old fears.

Depth and darkness... The windless embrace...

We will give to fear a form and yet none a vague hydra, a load monstrosity, surging from the unfathomable... reminding them who their gods are. Hydroid.

Release Date: August 29th, 2017

  • Hydroid Prime, compared to HydroidIcon272 Hydroid:
    • Higher Shields (550/650 vs. 365/465)
    • Higher Armor (290 vs. 240)
    • Higher Energy (175/225 vs. 140/190)
    • Higher Starting Energy (100 vs. 75)
    • Additional Vazarin Pol and Naramon Pol Polarities (Madurai PolVazarin PolNaramon PolNaramon Pol vs. Madurai PolNaramon Pol)
  • As with any other Prime Warframe, moving close to the location of an Orokin Void Death Orb will restore a pulse of 250 Energy to nearby allies, even if that Death Orb is inactive, destroyed, or non-present. This effect can only occur once per orb.
  • Hydroid Prime's TentacleSwarm130xWhite Tentacle Swarm tentacles are opaque and have a new organic texture that is affected by Hydroid Prime's Warframe Appearance colors.
    • Energy color applies a coat of energy on the tentacle's model and alters the color of the numerous glow spots on the texture. This allows players to customize their tentacles to look similar to the older tentacle model prior to Update 21.4 (2017-08-10).
    • Tentacle texture can return to default non-Prime translucency by equipping different skins (e.g. Hydroid Immortal Skin on Hydroid Prime)


  • Hydroid Prime, along with Frost PrimeIcon272 Frost Prime, can achieve the third highest total shield value out of all Warframes at 3,195 by combining Mod TT 20px RedirectionMod TT 20px Primed VigorMod TT 20px Augur Accord, and their maximum Overshields (+1200). HarrowIcon272 Harrow currently holds the second highest possible shield value of 4,110, beaten only by Hildryn's 6555. These numbers can potentially be higher with other buffs that increase shield capacity (such as Mod TT 20px Shield Charger and Sequence).
  • Hydroid Prime was revealed at TennoCon 2017 alongside Excalibur UmbraIcon272 Excalibur Umbra and Plains of Eidolon.
  • His Prime trailer was revealed at TennoCon 2020.
  • A fully built Hydroid Prime was given for watching TennoCon 2020 on WARFRAME's Twitch with a Twitch-linked account for 30 consecutive minutes, after 5:00 p.m. ET, on August 1st, 2020. It comes with a free Warframe slot and pre-installed Orokin Reactor.
    • Due to thousands of players reporting missing Twitch drops, on August 6th, 2020 Hydroid Prime was distributed to all players if they were logged in to WARFRAME during TennoCon 2020, regardless if they watched the streams or not.[1]

Enemies damaged by HydroidIcon272 Hydroid are permanently more vulnerable to DmgCorrosiveSmall64 Corrosive Status, with initial status reducing armor by 50% rather than 26%, allowing Corrosive Status to reach 100% armor reduction at full stacks. As long as Hydroid has damaged the enemy, the Corrosive Status Effects can be applied from any source, not just from Hydroid's weapons or abilities, and will receive the benefit.

Affected enemies are marked with a translucent water-dripping DmgCorrosiveSmall64 Corrosive symbol over their head, and a splashing sound is played when a new enemy is affected. The symbol color is affected by Hydroid's chosen Warframe energy color.

Bosses are immune to the increased armor reduction from Hydroid's passive, except in the Simulacrum.

Patch History

Update 36.0 (2024-06-18)

  • Fixed recasting Hydroid’s Plunder ability causing its Armor buff to stack indefinitely.

Hotfix 35.5.7 (2024-04-17)

Line of Sight (LoS) Changes & Fixes

As mentioned in our last Hotfix 35.5.6, the team continues to address and assess player reports of further LoS issues. While the quality and consistency of LoS checks has improved significantly, we're still not 100% satisfied and sometimes the results are still unpredictable. The team is investigating LoS checks at large occasionally having odd interactions with terrain, enemies, etc. which is causing inconsistencies in the checks. We are looking to have this resolved in the next Cert update (more info on what that means here).

For today, we have made LoS improvements to the following Warframe abilities:

  • Hydroid’s Plunder (Rendered Check)
    • In addition to rendered checking, it is also no longer FOV dependent to prevent issues where low FOV settings would cause Hydroid’s body to obstruct LoS.

Update 35.5 (2024-03-27)

  • Fixed bug where Hydroid’s Passive Corrosive mark on enemies would not show up for other players.
  • Fixed Hydroid’s Passive causing other Armor stripping abilities to not work.

Hotfix 35.0.4 (2023-12-20)

  • Fixed Hydroid’s Tentacle Swarm throwing Murmur enemies into the air instead of grabbing them.

Update 35.0 (2023-12-13)

  • Fixed armor stripped by Hildryn’s Pillage sometimes regenerating on enemies affected by Hydroid’s Passive.
    • We are aware of other issues related to Hydroid’s Passive and armor strip, but those require a Code Fix that did not make it in time for this update.
  • Fixed a script error caused by Hydroid's Tentacle Swarm.
  • Fixed a script error caused by Hydroid’s on-hover Ability information.

Hotfix 34.0.8 (2023-11-09)

  • Fixed Hydroid’s tentacles (at its max amount of 20) not seeking out new enemies to grab after killing enemies already in their grasp.
  • Fixed a script error caused by Hydroid’s Tentacle Swarm.

Hotfix 34.0.6 (2023-10-30)

  • Replaced an outdated Hydroid ability tip with a new one for Plunder: “Casting Plunder removes any Corrosive Status Effects currently affecting enemies, permanently reducing their maximum Armor based on the Corrosive Status removed.”

Hotfix 34.0.4 (2023-10-24)

  • Added the video preview of Hydroid's new "Plunder" ability in his Ability screen.
  • Fixed Hydroid’s Tentacle Swarm Kraken despawning before the ability has expired. A pirate needs his trusted companion to stick around to take care of these landlubbers!
  • Fixed a script error from enemies being ragdolled by Hydroid’s Tentacle Swarm.

Hotfix 34.0.2 (2023-10-19)

  • Fixed several script errors in Hydroid’s Tentacle Swarm.
  • Fixed a script error in Hydroid’s Tempest Barrage when cast on Railjack.

Hotfix 34.0.1 (2023-10-18)

  • Fixed a script error in Hydroid’s Corroding Barrage Augment Mod.
  • Fixed a script error in Hydroid’s Tidal Surge ability.

Update 34.0 (2023-10-18)

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:

Health: Base Rank - 270 (from 100) / Max Rank - 370 (from 300)
Shields: Base Rank - 365 (from 125) / Max Rank - 465 (from 375)
Armor: Base Rank - 240 (from 225)
Energy: Base Rank - 140 (from 125) / Max Rank - 190 (from 188)

Health: Base Rank - 270 (from 100) / Max Rank - 370 (from 300)
Shields: Base Rank - 550 (from 175) / Max Rank - 650 (from 525)
Armor: Base Rank - 290 (from 275)
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!


For those of you with an interest in the sea, who wish to use the murky depths to drown your foes, the wait is over! Hydroid has received a rework!

As with many of our Warframe Reworks, a Forma Inbox will be sent to all players at 11:30am ET on October 18th after Abyss of Dagath launches.

The goal of the Hydroid rework was to keep his unique style while making him both easier to use and bringing his power more in line with other Warframes. This means changing how his abilities work through changes to their damage types, removing charging mechanics, and making enemies easier to hit while they are wrapped up in his abilities. Additionally, it meant reworking his passive and removing the Undertow ability, replacing it with the new Plunder ability.

For a closer look at our deadly marauder of the deep, let's dive right in!

Changing Impact and Magnetic Damage to Corrosive Damage and Status

Previously, Tempest Barrage and Tidal Surge both dealt Impact damage, while Tentacle Swarm dealt Magnetic Damage. These have been changed to Corrosive Damage, which can apply Corrosive Status. Corroding Barrage has been a widely used Augment Mod by Hydroid players, which caused Corrosive Status for Tempest Barrage, and due to its popularity, we looked to incorporate its effect into Hydroid at a base level.

We felt changing Damage to Corrosive Damage in Hydroid’s abilities makes them more thematic to the sea while also incorporating Corroding Barrage’s current effect in a meaningful way. With this change in mind, Corroding Barrage will now apply Viral Status instead of Corrosive - more details on that below.

Passive Changes

Hydroid’s previous Passive had a chance to spawn a tentacle when performing a melee slam attack. We have removed that passive entirely and replaced it with an entirely new effect.

The nature of Hydroid’s previous Passive pushed players to a very specific playstyle (regular usage of melee slam attacks), while not guaranteeing anything useful from each individual slam. We wanted to make the passive feel more reliable and impactful.

New Passive: Enemies damaged by Hydroid are more vulnerable to Corrosion Status, with initial status reducing armor by 50%.

Hydroid’s new Passive affects an enemy once Hydroid damages them, lasting until their death. It makes the first instance of Corrosive Status on an enemy remove 50% of their Armor rather than 26%. Not only does this make the first Corrosive Status stronger, but it also means Corrosion Status can reach 100% Armor Reduction with full stacks!

To clarify, this means Hydroid does not need to apply all, or even any, of the Corrosive Status Effects on an enemy. As long as Hydroid has damaged the enemy, the Corrosive Status Effects can be applied from any source and will receive the benefit.

You can see the Passive in action in the Ability clips below.

Removing Charge Mechanics

In an effort to make Hydroid more approachable, we have removed the charge mechanic on Tempest Barrage and Tentacle Swarm. The full charge values will now apply baseline to each cast of the abilities.

For example, previously, an uncharged Tentacle Swarm would have 40% of the tentacles and 33% of the radius compared to a fully charged cast. With this change, both tentacle count and radius will always be the maximum, what a fully charged cast was previously.

This change makes Hydroid’s play more fluid, with more time spent attacking rather than charging abilities for their maximum effect.

Ability Changes

Tempest Barrage:

  • Damage dealt causes enemies to stagger, rather than ragdoll.
    • This should make enemies easier to kill, as they will stay in the range of Hydroid’s other abilities and be more open to Headshots.
  • The Corroding Barrage Augment Mod has been renamed Viral Tempest and now has a chance to apply a Viral Status Effect, rather than Corrosive Status Effect. It also no longer grants Ability Strength.
    • Changing the Impact Damage of Tempest Barrage to Corrosive Damage meant the Corrosive Status Effect from the Augment was already included. We changed this to Viral to maintain its relevance with the other changes. In light of the punch Corrosive and Viral packs in comparison to Corrosive and Impact, the Ability Strength buff was removed for balance purposes.
  • Added new sound effects to go with the ability.

Tempest Barrage staggers enemies instead of ragdoll, making them easier to target.

Tidal Surge:

  • Allows some steering of the wave for more control over where Hydroid and his enemies end up when the ability is finished.
  • Exiting Tidal Surge early by jumping now also works while airborne.
  • Tidal Surge’s base speed has been increased and will no longer scale off Ability Range.
    • This change was made to ensure controlling the wave behaves consistently, including where enemies are deposited when the ability ends.
  • Tidal Surge no longer violently flings carried enemies at the end of the surge, and will instead deposit them where the surge ends.
  • This should make Tidal Surge a better ability for grouping enemies and quick killing, as opposed to flinging them across the room.
  • Tidal Surge now applies Corrosive Status Effects to enemies based on how long they are carried by its waves.
  • Tidal Surge now cleanses all of Hydroid’s negative Status Effects.
    • This brings one of the benefits from the Tidal Impunity Augment Mod into the ability directly, granting Hydroid some survivability in his abilities with Undertow’s removal.
  • Added new sound effects to go with the ability.

Tidal Surge now carries enemies with the wave, depositing them where the wave ends instead of throwing them forward.

Undertow (Replaced with Plunder):

  • This ability has been removed and replaced with Plunder.
    • Undertow was an ability which we feel made Hydroid a bit less fun to play as, or play with. There are two main reasons we decided to replace this ability:
    • It forced the player to remain stationary, while many objectives rely on regular movement.
    • It absorbed enemies without instantly killing them, which could lead to instances of hiding enemies that a teammate was trying to kill.


  • A new ability added to Hydroid’s third ability slot.
  • All enemies in range will have Corrosive Status Effects remove their armor permanently, increasing Hydroid’s armor and granting bonus Corrosive damage to weapons.
    • This ability is stronger based on the number of Corrosive Status Effects applied to the enemies affected by Plunder.
    • This means with a full stack of Corrosive Status Effects, their Armor will be removed permanently.
  • The Curative Undertow Augment Mod has been renamed Rousing Plunder and it causes Plunder to heal Hydroid and his allies within Affinity Range.

Plunder removes Armor based on Corrosive Status Effects on an enemy. It also provides an Armor and Damage Buff, tracked in the lower-right corner of the HUD.

Tentacle Swarm:

  • Now holds enemies in a steadier position, making it easier to eliminate enemies locked down by Tentacles.
  • If a tentacle’s held enemy dies, it will move to grab a new enemy in the Tentacle Swarm’s area of effect.
  • Updated Tentacle sound and visual effects.

Tentacle Swarm now holds enemies still for easy targeting, rather than violently shaking them about.

Hotfix 33.0.11 (2023-05-24)

  • Fixed script error with Hydroid’s Undertow ability.

Update 33.0 (2023-04-26)

  • Fixed hand clipping issues for the following Warframes (includes Primes for those who have that variant) when using Hildryn Prime’s Noble animation.
    • Hydroid

Hotfix 32.3.3 (2023-02-17)

  • Fixed Hydroid’s Tentacle Swarm appearing as a square instead of a natural pool shape.

Hotfix 32.0.9 (2022-10-05)

  • Reduced the Mastery Rank restriction of all Prime Warframes to 0.
    • Only 11/34 frames had any Mastery Rank restrictions, so we decided to make these consistent with the rest (there were no Mastery Rank restrictions on any non-Primed Warframes).

Update 32.0 (2022-09-07)

  • Fixed the Tentacles of Hydroid’s Tentacle Swarm targeting your companion before enemies.

Hotfix 31.5.6 (2022-05-04)

  • Fixed Hydroid's Pilfering Swarm affecting Vitoplast drop amounts from enemies in Void Flood missions.
    • This was the original design intention, as was mentioned in the pre-launch sponsored videos on Void Flood missions. Its core design encourages the use of your parkour skills as the primary way to collect scattered Vitoplast around the tileset, with enemy drops being secondary.

Hotfix 31.5.4 (2022-05-02)

  • Fixed Hydroid’s Pilfering Swarm being able to duplicate Voidplume Pinion and Arcane drops from Void Manifestation fights.
    • Restored these to match Khora’s Pilfering Strangledome and Atlas’ Ore Gaze Augment mods intentionally not applying their loot bonuses on Void Manifestations.

Update 31.5 (2022-04-27)

  • Fixed Hydroid’s Tidal Impunity Augment Energy cost reduction not applying on the second and following casts.
  • Fixed sprint (when toggle sprint is enabled) getting canceled after using the following Warframe abilities:
    • Hydroid’s Undertow

Update 31.2 (2022-03-16)

Hydroid Tidal Surge Changes:
  • Hydroid’s Tidal surge can now be canceled early by jumping (similar to Lavos’ Vial Rush).
  • Reduced the cost of a second Tidal Surge cast by 50% while in Tidal Surge.
  • Recasting the ability to change directions will now do so seamlessly while in Tidal Surge form (Hydroid will no longer pop his head out in between casts).
  • Fixed spamming Hydroid's Tidal Surge causing the wave FX to stick to Hydroid permanently.

Update 30.6 (2021-08-04)

  • Fixed the ability to reach locations where enemies cannot not damage you by using Hydroid’s Undertow.

Hotfix 30.1.1 (2021-05-05)

  • Fixed refreshing Hydroid’s Tidal Impunity removing knock down prevention.

Hotfix 30.0.7 (2021-04-22)

  • Fixed only traveling 50% of the intended distance when casting Hydroids Tidal Surge with Fire Walker active (via Helminth Subsume and in place of Undertow).
  • Fixed Hydroid’s Tentacle Swarm timer disappearing when casting Tentacle Swarm then Transferring to the Operator.

Hotfix 29.6.5 (2021-01-09)

  • Fixed enemies becoming permanently crowd controlled when under the combined effect of Hydroids Tentacle Swarm and Larva (Helminth Infused).

Hotfix 27.4.4 (2020-05-07)

  • Fixed Hydroid’s Immortal Skin not applying correctly to his body.

Update 27.3 (2020-03-24)

  • Fixed Heavy Melee Slam Attacks not triggering Hydroid’s Passive to spawn a Tentacle.

Update 27.2 (2020-03-05)

  • Armor Change:
    • Hydroid: 200 to 225
    • Hydroid Prime: 250 to 275
    • Why: The conversation surrounding Arcane Guardian led to a significant review of Armor stats on Warfarmes. The Majority of Warframes received an increase in the Armor stat to increase survivability. Compounded with Shield Gating and the numerous other changes covered, we expect a much more fair feeling playing field for all Warframes.
  • Fixed a map hole that was only accessible if you were in Hydroid’s Undertow. Like that one scene in X-Men when that one dude is disintegrated into water and slips off the table in a watery terrifying massacre...

Hotfix 27.1.1 (2020-02-11)

Hotfix 27.0.12 (2020-01-23)

  • Hydroid ability videos have been added to his Arsenal!

Update 25.8 (2019-10-01)

Warframe Looting Ability Changes

Warframe Loot Abilities will again be able to yield multiple-drops from already looted corpses. A single enemy can be looted by at most one Ability from each group - which is how it worked before, this just clarifies it. Warframe Looting Abilities have been split into separate functionality groups for clarity:

  1. Loot while alive: Ivara
  2. Loot petrified: Atlas
  3. Loot on death: Wukong, Khora, Hydroid. An enemy can only be killed once, they can’t ‘die’ multiple times.
  4. Loot corpse: Nekros, Chesa

These changes stem from a bigger conversation that was addressed yesterday regarding not providing closure on the Loot Frame changes from The Jovian Concord. All the information can be found here: https://forums.warframe.com/topic/1131506-the-mod-booster-and-free-to-play/
