Double Energy

DefectSkillUncommon
Double your Energy.
Exhaust.

You pay the cost first, then your remaining Energy doubles. With 3 Energy the base version pays 1, leaves 2, and gives 2 more for a net gain of 1. Upgraded it costs 0, so 3 becomes 6 and 5 becomes 10. The gain grows with your pool, so play it before spending anything else. Exhaust, so it works once per combat.
