We'll see. They could have made it into more of a gladiator arena.
I don't fully understand how you can kill something, and use its energy to revive other stuff, and yet some creatures end up having even more Psy energy as ghosts...
but you don't see me pointing out the flaws, yogc.
These are just possibilities, and if you have better ones, please speak up. These don't even have to be implemented. It's just that if some people DO want to use up their Soul Charges, and don't want the guilt of killing their teammates (like moi), this is trying to be as complete list as possible of all possibilities that anyone might reasonably consider as uses for the Soul energy.
