Energy Drain is a tech power in Mass Effect 2 and Mass Effect 3. Energy Drain saps enemies' kinetic barrier power to boost your shields. Like Overload, this ability will do double damage to shields.
Note: This power travels in a straight line from the user to the target, hitting instantly.

Player Notes
- Energy Drain deals the damage amount listed above to armor, barriers and synthetic health. Double damage is dealt to shields. No organic health damage is dealt.
- Energy Drain is capable of providing the largest shield boost in the game.
- Shields are recharged based on the amount of damage that was dealt. Shields can be temporarily boosted beyond their normal strength.
- Your shields are only restored if enemy shields or synthetics are hit.
- Energy Drain is useful for Adepts on higher difficulties because of the prevalence of shields among enemies as well as acting as an anti-synthetic weapon since Adepts do not have any powers or weapons training tailored to destroy synthetics.

Player Notes
Note: Energy Drain deals 3x damage to all shields and barriers, normal damage to armor from synthetic enemies, and only half damage to armor from organic enemies.[1]
- Mechanics
- Energy Drain will only replenish the player's shields when it hits an enemy with barriers/shields or any synthetic enemy.
- Energy Drain will only prime and detonate combos when used against an organic with shields or barriers, or any synthetic.
- Strategies
- Energy Drain is a fast way of taking down Turrets as well as Atlases.
- Energy Drain with the Rank 4 Radius evolution is useful in taking on large groups of geth that tend to cluster at the onset of combat.
- Energy Drain is a useful bonus power for classes that are lacking in anti-shield capabilities like Adepts, Vanguards, and to a slightly lesser extent Infiltrators.
- In multiplayer, while not the most damaging ability, it will almost always stun the enemy, making it a great way to set up follow-up shots or melee.
- On higher difficulties, Energy Drain is a useful survival tool, allowing the player to weaken enemies and restore precious shielding at the same time.
- With a short enough recharge time, Energy Drain can render a player all but invincible against the geth, allowing you to restore your shields and stun enemies faster than they can kill you.
- The electrical effect that Energy Drain applies does not last as long as the one from Overload or Disruptor Ammo, making it an inferior choice as a primer when attempting to self-detonate tech bursts.
