Draining Finisher
Source
Interstellar Species pg. 33
With a practiced swing, you expend all your weapon’s power into one strike. When you successfully use a melee weapon with the powered weapon special property to strike a target, you can expend all the weapon’s remaining charges to deal additional damage, after which the weapon deactivates. The amount of additional damage is equal to 1d4 for every 3 item levels the weapon has. If the weapon has at least one-fourth, one half, or three quarters of its charges remaining, the additional damage die size increases to d6s, d8s, or d10s respectively. A weapon subjected to draining finisher overheats and cannot be reactivated without cooling down and rebooting for 1 minute.
