This is probably super overpowered, and that may be fixed with some other stuff.
1. Imagine like a billion Mark 4 Sword bots charging you. Suddenly, you switch to an archer on the other side of the arena. You literally just avoided death.
1. Fix - What if it takes like five seconds to posses a robot? This would make it so you can't just teleport away from danger. You also cannot move while these five seconds count down, so you have to be in a safe area to do this.
2. Alright, I'm on round 173 and I'm going to use the same tactic, again. Here we go. 3-2-1-GO! *Switches with archer* Sniped! *Switches with Hammer Bot* Crushed! *Switches with swordsman* Sliced!
2. Fix - It would be so overpowered to just be able to quickly transport between enemies and destroy them, before they even realize it. I think this could be fixed in two ways:
b) 4 bars of energy
c) Both a) and b) (Probably would work the best)
