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 Edit

• Energy Drain will replenish the player's shields when it hits an enemy with barriers/shields or any synthetic enemy.
• 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.
• Unlike Overload, Energy Drain will only trigger Tech Bursts, Fire Explosions, and Cryo Explosions when used to kill primed synthetics or shielded organics. Using Energy Drain on unshielded and primed organics will not trigger tech combos.
• 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.
