Power Combos

Power Combos are a gameplay element introduced in Mass Effect 3. By attacking an enemy with two powers in rapid succession, the combined effects of each power can result in a powerful, deadly explosion with a wide radius. All power combos require two different varieties of powers be used: a source and a detonator. The source power determines which of the four power combos will be triggered, and the detonator triggers the combo and causes the explosion. Some powers can be both sources and detonators for different combos.

Biotic Explosion
Biotic Explosions can occur regardless of an enemy's health level; other combos usually require that the combo be a killing blow on the victim in order to trigger. These combos are effective against biotic barriers and armor. Note that a using a detonator power in combination with an identical source power will not cause an explosion (for example, a warp will not detonate another warp).

Source Powers

 * Pull
 * Singularity
 * Warp
 * Reave
 * Stasis
 * Dark Channel
 * Lift Grenade
 * Shockwave (with "Lifting Shockwave" power evolution)

Detonator Powers

 * Throw
 * Shockwave
 * Warp
 * Biotic Charge
 * Reave
 * Slam
 * Cluster Grenade
 * Nova
 * Lift Grenade
 * Concussive Shot (with Amplification evolution and Warp Ammo equipped)
 * Barrier (if detonated)

Cryo Explosion
Cryo Explosions create a blast of ice that has a chance of freezing nearby enemies. These combos are effective against armor. This combo requires the enemy to die before the combo is initiated.

Source Powers

 * Cryo Blast
 * Cryo Ammo

Detonator Powers

 * Concussive Shot
 * Sticky Grenade
 * Frag Grenade
 * Proximity Mine
 * Carnage
 * Throw
 * Shockwave

 * Overload
 * Combat Drone Death Explosion
 * Decoy Death Explosion

Tech Burst
Tech Bursts create a blast of electricity that inflicts severe damage on the shields of nearby enemies and has a chance of stunning them. Like Biotic Explosions, Tech Bursts can be triggered without being a killing blow, and the source/detonator powers must be different (for example, using Energy Drain twice will not trigger a Tech Burst).
