Player Notes Edit

  • Using this power, Kasumi cloaks, appears behind her target and delivers a devastating sneak attack, then re-cloaks and returns to her previous location.
  • Besides directly damaging the enemy, this power also has a distracting effect, as enemies will often turn to attack Kasumi when she appears in their midst, ignoring their previous targets; she usually takes little damage from this, and often her shields and health will have regenerated by the time she returns to her starting point, although it is possible for her to die before going back into cloak.
  • The damage is effective against armor, shields, and barriers; the incapacitation only takes effect if the target is unprotected or if the strike's damage carries through to their health.
  • The power has a 2x damage multiplier against shields, armor and barriers.
  • The power type is actually split between combat and tech - it gains the bonus for reduced cooldown from the tech upgrade but the damage type is combat, so the damage tech upgrade has no effect.
  • Kasumi can only strike with this power targets within a certain walking distance. She can not target enemies in the areas unreachable by Shepard, or in places where she must take a long walkaround to reach. She will tell you if she can not make a particular strike.
  • Kasumi will execute the attack from any assigned position (keyboard Q or E on PC), and she will return to her original position. However, she will no longer be bound by the placement command. You have to re-assign the command to keep her behind cover after such a strike.
  • This is very useful against the big powerful units such as Harbinger - the strike gives you enough time to aim out of cover and shoot the enemy in the back of the head without being shot at yourself.

Player Notes Edit

  • Shadow Strike functions very similarly to Kasumi's power in Mass Effect 2: the player cloaks, reappears behind the target, and delivers a powerful melee attack. Unlike Kasumi's power in Mass Effect 2, in Mass Effect 3 the player does not re-cloak and return to their starting point.
  • If the enemy is unaware of the N7 Shadow when Shadow Strike is activated, the attack cannot be blocked and the user appears behind them; otherwise, foes will attempt to shoot and/or melee the Shadow, and defenses will block the attack (e.g. a Guardian's shield).
  • Shadow Strike benefits from melee damage bonuses of equipment and weapon mods as well as the melee damage evolutions of Shadow Strike, Tactical Cloak, and Sword Mastery.
  • Shadow Strike can be used on any enemy that can be selected for targeting; even obstructed enemies or difficult-to-reach places are thus vulnerable to Shadow Strike.
  • When used against specific foes:
    • Shadow Strike may be used on Phantoms and Geth Hunters even while they are invisible, if the crosshair is aligned with their hitbox.
  • As of Patch 4, Shadow Strike doesn't work against Atlases.
  • Shadow Strike is capable of instantly killing most basic-level enemies. On Gold difficulty, a double Shadow Strike from cloak (Tactical Cloak's bonus power and duration evolutions allow two strikes before breaking cloak) is effective against powerful enemies.
    • With the proper evolutions and equipment, even Platinum Phantoms can be killed by a single cloaked Shadow Strike.
  • Shadow Strike can be used to travel across the battlefield quickly, in order to escape danger and/or to reach a tactical position, since it immediately transports the user to the target.
    • Be very careful about Shadow Striking Ravagers, as they are very likely to spout an acid patch that you will be standing right in the middle of, especially if they die.
  • Unlike the Vanguard's Biotic Charge, Shadow Strike has the disadvantage of not replenishing the user's shields. This can be offset by the following:
    • The Shadow Strike Damage Protection and Shield Drain evolutions of the power.
    • The Sword Mastery durability and shield recharge evolutions, which synergize with the power.
    • The Tactical Cloak Duration and Bonus Power evolutions, allowing the Shadow more time to select a target while shielded from enemy sight.
