Energy Tap

Energy Leak is a power that can be used in battle that reduces the amount of damage dealt by your enemy and increases your own damage.

Strategy Guide Description
"Imagine… Note: Energy Leak is best served with a side order of Droid and a sprinkling of the Rapid Fire ability. Such a combo can outshine even the mighty Unmaker Omega."
 * 1) You have a pack of high-level robots. Your enemy has only a single weak one, or (better yet) none. That’s when it’s a good time for Energy Leak. Every stray shot that manages to hit the enemy mainframe translates directly into experience. Boosting your robots when they get to shoot at the big guy equals more level-ups for them. Level-up means full repair, better armor and better damage. Level-ups are totally worth it.
 * 2) You have a pack of high-level robots… and the enemy has them too! Energy leak causes the enemy robots to be less effective while giving a vital boost to your own forces. Therefore it’s good to use Energy leak, especially when it grants few extra kills to your units. Even better when the enemy robots are hurt badly and leveled up. (More EXP for each kill and more enemy damage gets negated by the leak.)

Levels

 * Level 1: Energy Tap. Energy tap gives your robots a minor boost and a minor hex at the opponent's own robot.
 * Level 2: Energy Leak. More powerful than Energy Tap. Impacts the droid by quite a bit.
 * Level 3: Energy Drain. Shuts off the opponents' robots from attacking, and buffs up your robots. Like every other perfect roll, it also grants an extra turn, so you can heal your robots or go for another drain (though it will only help your robots). Or you can also use some brute force and pull out the lasers. It depends on your preferences.
