Stasis is a biotic ability in Mass Effect, Mass Effect 2, and Mass Effect 3.

Mass Effect[]

The Stasis icon

Stasis is an unlockable biotic talent in Mass Effect. Stasis causes an enemy to be temporarily locked in a mass effect field, freezing the target in place and making them unable to attack. The "freeze" even applies to enemies in mid-air. Enemies in Stasis become impervious to damage unless the Stasis was cast by a player possessing the Bastion specialization class with Stasis Specialization unlocked, in which case the player can still shoot to damage and eventually destroy the target, albeit without seeing a health bar. Squadmates don't have access to this specialization and they will largely ignore targets in Stasis even if they can be damaged. Also note that Squadmates trained to use Stasis will never use it on enemies unless directly ordered to do so, even if Squad Power Use is set to "Active" in the game menu. This can be a handy way to make sure you have something "in reserve" in emergencies when you need to disable an enemy and all of your party's abilities are still recharging.

Note that while Stasis can work on almost any enemy target, larger and more powerful enemy types typically have high levels of resistance to biotics meaning the duration will be noticeably shorter when used against them than against weaker more common opponents. Also use caution when using Stasis against enemies with powerful attacks such as snipers that use Assassination or Geth Armatures, as when the effect wears off enemies will immediately resume attacking as if they were never interrupted. This means if they were charging a shot right before they were "paused" by Stasis, when the Stasis ends they will unleash the shot instantly.

On higher difficulty settings some powerful biotic enemies, notably Rachni Brood Warriors, can put you and your squad into Stasis. Like Bastions, they can cause damage while their target is immobilized, and medi-gel doesn't seem to help. It also puts you at risk from any flying debris, because it becomes impossible to dodge and your shields won't take the damage. The only real defense against this is to preemptively disable them with biotics or Damping, then take them down as fast as possible. Lighter armors with higher levels of tech and biotic protection (bottom bar) can also shorten the duration of enemy biotic effects such as Stasis.

These classes have access to the Stasis talent:

Mass Effect 2[]


Creates a powerful mass effect field that penetrates shields and other defenses to immobilize the target for a few seconds, preventing all actions and making it immune to damage.

Rank 4

At Rank 4, choose from one of the following specializations

Deep Stasis[]

  • Greatly increases the strength of Stasis, allowing targets to be immobilized for a longer duration.
    • Recharge Time: 6.00 seconds (Shepard) 12.00 seconds (Liara)
    • Duration: 12.00 seconds

Enhanced Stasis[]

  • Increases the penetration of Stasis so that targets build up less resistance to its effects. Targets become immune more slowly.
    • Recharge Time: 6.00 seconds (Shepard) 12.00 seconds (Liara)
    • Duration: 9.00 seconds

Player Notes[]

  • Once Stasis wears off, the enemy will fall to the ground briefly, where they will receive bonus damage (x3-x4) until they get up, at which point only normal damage is received.
  • Targets will build up immunity to Stasis if it is used repeatedly on them in a short period—this prevents a single enemy from being incapacitated indefinitely.
  • Stasis is unique among powers in that it will work despite any defensive layers that an enemy has, with the drawback of not directly dealing damage.
  • Sometimes players are unable to select Stasis as a bonus power in the character creation stage after completing the DLC with a previous character. (PC Version)
  • Although the short-term damage boost as Stasis wears off on an enemy is intended, due to a bug (the enemy is considered a non-hostile while in Stasis), difficulty and other factors are not scaled correctly, and as a result, the damage boost is multiplied further than intended. This tremendous damage boost enables players to one-shot many enemies if the short window of opportunity is taken advantage of. However, the end result would be the same for most enemies if the bug did not exist, as you would be able to legitimately one-shot many enemies with the intended damage multiplier, with the exception of sub-bosses like YMIR Mechs and Scions, especially on Insanity. BioWare has not prioritized to fix this bug.[1]
  • Stasis does not affect the vast majority of armored enemies lacking a red health bar (Harbinger, Praetorians, Thresher Maws, the A-61 Mantis Gunship, Geth Colossi, the Shadow Broker or Oculi).
    • Scions are an exception and are susceptible and can even be ragdolled
    • Stasis does affect the Human-Reaper in the final battle of the Suicide Mission (it is not ragdolled).
  • Using Stasis on flying drones (e.g. Rocket Drones) will cause them to die instantly once the stasis wears off.
  • Using Stasis on any airborne enemy other than drone types (e.g. enemies suspended by biotics) will freeze them in the air for the duration.
  • Using Stasis on the last enemy in the area will sometimes revive fallen squadmates.

Player Notes[]

  • Stasis does no damage to enemies. If the player is attempting to get Stasis points for the multiplayer challenge Stasis Use, the player will have to immobilize enemies with Stasis and then damage them with weapons, powers, or melee attacks to kill them. A small portion of the experience (xp) granted after the kill will go towards the Stasis Use challenge.
  • The Rank 6 Stasis Bubble evolution can be seen as an alternative to Singularity that works on any foes besides those with armor. It is very useful as a setup for potentially multiple Biotic Explosions when combined with finishing moves like Throw, Shockwave, Nova, etc.
  • As an alternative route, Vulnerability (rank 6 evolution) can be used to increase the damage of a biotic explosion.
  • The bubble evolution sees greatest use against Cerberus as only the Atlas, Dragoon and the Combat Engineer's Turret are immune. The Engineers themselves are not immune, however, and can even be halted with stasis in the middle of setting up a turret, causing the turret to explode. Even Guardians are frozen by the bubble with their shields being simultaneously removed (shielded Guardians are unaffected by a non-bubble Stasis).
  • Stasis Bubble can hold two enemies at a time in stasis. Additional susceptible enemies inside the field radius will be staggered by the field but cannot be locked in stasis until one or more of the enemies already in stasis have been removed either by killing them or by damaging them sufficiently that they fall out of stasis. A stasis bubble can thus be used to capture three, four, even five opponents if the player and squadmates are efficient in dealing with them, but never more than two at a time will be "in stasis".
    • Cerberus troops who debark from shuttles or otherwise "jump in" to combat will not jump if they are directly above a stasis bubble that is currently "full". Instead they will wait patiently and then jump once there is a free spot for them to be frozen in the bubble, or after the bubble collapses. So in many campaign missions where shuttle drops feature prominently, such as Tuchanka: Bomb and Priority: Eden Prime, Stasis Bubble can create a massive tactical advantage.
    • No more than one Stasis Bubble per character can be on the field at a time.
  • Stasis still finds significant usage against the geth as only Geth Primes, Geth Pyros, and Geth Bombers are immune. Stasis is particularly effective against Geth Hunters.
  • Reaper units are mostly armored (namely the Banshee, Brute, and Ravager), and therefore immune to stasis. However, if a bubble Stasis Bubble is placed on or near a Ravager, the Swarmers it produces will die instantly upon contact with the Stasis Bubble. Stasis Bubble is remarkably effective against Cannibals though: placing a bubble over an enemy corpse is a very effective trap.
  • As of Mass Effect 3: Retaliation, Stasis is invaluable against the Collectors, as only the Scion and Praetorian have armor, and thus all others are vulnerable even while possessed. This is especially helpful against Possessed Abominations, who have the tendency to wipe out two or more allies with their death explosions if not defeated with headshots.
  • Stasis will stop working against enemies who've been hit with it three times already, or received sufficient damage. It is highly recommended that you kill them before it becomes ineffective, especially when facing tougher foes.
  • Only damage to the health of enemies is considered "damage done" to enemies in Stasis. To prevent unintentional releases of enemies in Stasis, do not inflict any health damage to them as the damage threshold is extremely low.
  • The turrets and drones summoned by Geth Primes are immune to Stasis even though they are not armored. The same is true of other enemy drone types such as the Disruption Drones summoned by CAT6 Specialists.
  • Though he is not armored, Kai Leng is immune to Stasis.
  • Stasis can be used on enemies in mid-air and it should freeze them in place just as in the previous two games, but they can sometimes drop while still in their frozen state.
