I ended up making a thief... then now I am leveling in toy factory, but I can't kill myst cases yet... So I just use steal on them and kill the rest, as I didn't see anything related to it on the rules, but I was wondering if even not being on rules that is fine, because theres other thiefs in TF always, so they won't be able to steal them too
Edit: Or it doesn't work like I'm thinking and many different players can steal from the same monster?
