I'm fairly close to the beginning, I've only just found out about my character's innate psionic abilities. I'm doing the sidequest for one of the psi trainers, more specifically the sidequest where I need to one of those overgrown rat creatures with a crossbow bolt that causes muscular decay or something.
Now, my problem is I've shot multiple rats with this special crossbow bolt, but there's no body or anything to collect an item off of after it's been killed. Also, those rat things are completely destroying me. Seriously, how the hell are you supposed to fight five of those things as once?
