"Grand Boss" is a community-made term

Bosses are a unique enemy class outfitted with superior weapons, high health, rechargeable shields, special abilities, and other traits. They are far stronger than regular units as they will use varying strategies to deal damage and avoid taking it.

There are five types of bosses in the game:

  • Regular Bosses - Bosses which can be mostly found as the target of Assassination missions.
  • Field Bosses - Bosses that can be encountered on select mission types, though not usually the main objective.
  • Assassin - Bosses that actively hunt down players who possess their respective Death Marks.
  • Grand Bosses - Massive, titanic bosses with a special set of mechanics, designed to offer the players the highest level of challenge.
  • Liches/Adversaries - Randomized enemies with Warframe-like abilities that attempt to take control of the Star Chart.

Regular Bosses[]

These Bosses are found mostly on Assassination missions (with a few exceptions). Each boss usually has a set of lines to "taunt" the Tenno sent to kill them. They generally drop mods and resources upon death. Depending on which boss the player is fighting, Blueprints of Warframe parts and special Weapon parts will often be rewarded upon mission completion.

KuvaLiches
Main article: Kuva Lich/Main

Kuva Liches are the heavily modified super soldiers of the Grineer, granted abilities similar to the Orokin process of Continuity through their infusion with Kuva. Formerly adept Grineer troops, careful selection by the Kuva Guardians leaves them as bait until their orchestrated death by an individual Tenno results in them absorbing the energy and elemental powers of the Warframe they were killed with as part of the process that renders them an immortal force able to occupy entire planets. Accompanied by elite Thrall troops, Liches are also armed with heavily advanced Kuva weaponry considered the peak of Grineer innovation.

When a Kuva Larvling is killed, a Kuva Lich will rise to act as the Adversary of the Tenno who has killed them and will occupy Earth. When a planet is occupied by a Kuva Lich, progress of the Tenno is actively inhibited through seizing a portion of the loot gained from missions. Their Kuva-born powers grant them invincibility in battle, which can only be broken by the Tenno who they are bound to by discovering a sequence of enigmatic phrases inscribed on Requiem Mods. Failed attempts at killing the Lich with Requiem Mods will result in it ranking up, absorbing more power from the Tenno's failed attacks and moving to a different planet (Earth, Mars, Ceres, Sedna, Kuva Fortress) becoming stronger. When the correct randomised order is discovered and applied to their Parazon, the correct combination drains the Kuva out of the Lich. This will cause them to flee to Saturn Proxima where they can either be Vanquished or Converted. Every Kuva Lich has a unique name and various randomized properties.

Main article: Sisters of Parvos

The Sisters of Parvos are Corpus super soldiers that work under Parvos Granum. Sought out as Candidates by Vala Glarios, the Sisters seek to fulfill Parvos's desire in having a reliable sibling, and are armed with advanced Tenet weaponry and Hound companions.

Acting as an Adversary to the individual Tenno whose actions in battle have caused them to rise, Sisters establish a foothold in the Star Chart. From there, they hinder the progress of the Tenno, seizing a large portion of credits gained from missions. Their powers, bestowed upon them by Parvos' technology, grant them invincibility in battle that can only be broken by the Tenno who they are bound to - by discovering a sequence of enigmatic phrases inscribed on Requiem Mods, which the Tenno must unearth and apply to their Parazon in corresponding order, thus being able to purify and permanently break the Sister's security encryption. Every Sister has a unique name and various properties.

Retired Bosses[]

These bosses have been removed from the game.

Main article: Arn Etina

Arn Etina was once the name of the final boss of Pluto, a black MOA found on Hades. Upon death there was a chance he would drop one of the components required to build ExcaliburIcon272 Excalibur. Arn Etina's name was changed to Ambulas as of Update 6.0 (2013-01-29).

Despite being a MOA, Arn Etina used a human-like game picture for their transmissions. The game picture and appearance have since been repurposed for Darvo.

Main article: J3-Golem

J3-Golem was the final boss of the planet Jupiter. It was found on the mission Themisto. After defeating it and finishing the mission, players received a VoltIcon272 Volt Helmet, Chassis or Systems blueprint. As of Update 11, Volt blueprints no longer drops from Golem, but are now built in the clan dojo. Upon death, J3-Golem had a chance of dropping Neural Sensors.

Notes[]

  • All bosses and assassins have a rare chance to drop an Orokin Cell upon death. This chance is fully separate from the planet's resource drop rate.
    • As such, it is possible for General Sargas Ruk and Lieutenant Lech Kril to drop two instances of Orokin Cells, the first instance coming from the planet's rare drop and the second instance coming from the rare chance.

Patch History[]

Update 33.6 (2023-07-27)

  • Removed a feature where certain bosses scaled their level based on your equipped Mods.
    • This is a remnant of an older Warframe system that scaled difficulty based on your Mod loadout. As a result, enemies like Captain Vor might be anywhere from level 10 to 30, depending on how “powerful” your equipped Mods were during your encounter.
    • With this feature removed, now all bosses will always spawn at a consistent level on the regular Star Chart.

Update 31.6 (2022-06-09)

  • Invulnerability icons on boss health bars will now only appear on health segments that have not been depleted.
    • Before: All segments got the icon no matter what.
    • Now: Only segments that still have health get the icon.

Hotfix 29.5.4 (2020-11-25)

  • Stalker and Acolytes have been given the fancy “boss Health bar” treatment!

Update 27.3 (2020-03-24)

Kuva Lich Changes:

Based on feedback with the recent overhaul to Status Effects in Warframe Revised 27.2.0, the conversation of how Status Effects should react with Bosses or VIPS has started. Our first step down this road is starting with Kuva Liches. Currently, there are two special rules to this “Boss Status enabling”:

  • No Status Effect will exceed a maximum of 4 stacks, with the exception of Impact which can stack up to 6 times.
    • Keep in mind there is a cooldown to how quickly you can stack up Impact Status Effects to avoid stunlocking the Kuva Lich.
  • Radiation does not change the enemy’s Faction, and instead of increasing Damage done to enemies with stacks, it increases the Damage taken from enemies who have turned on him/her.

We look forward to your constructive feedback and we work towards applying this to other Bosses/VIPS.

Update 26.0 (2019-10-31)

  • Added new boss health bar introduced in the Emissary boss fight to all bosses except Jackal, Vor and Lech Kril, the Raptor, Hyena Pack, Ambulas and Lephantis.

Update 25.7 (2019-08-29)

  • Fixed abusing Host migrations to get multiple Beacon assassin spawns. Beacons will be ineligible to place after a Host migration if someone had already summoned an assassin previously.

Update 18.5 (2016-03-04)
