Recharging the Batteries

I have the very important task of collecting the machinery inside these ruins, but I'm having a problem keeping all of my bots charged up.$B$BThe phase hunters - those wyrm-looking things - have lots of energy! You can find them all over the edges of this island, floating in from the nether.$B$BFill the battery on this recharging blaster by using it on a phase hunter when they're very weak, and then finish it off to soak up the last of its energy.
