Can I get into trouble stealing?
I've just started playing The Witcher and while it seems there are ways to alter people's opinion of you (e.g. bribes and signet rings), I can't tell if me taking stuff out of containers in peoples homes will get me in trouble with anyone.
In short: Does taking other people's stuff have any consequences?
According to The Witcher FAQ (in the Looting,Trade section) there are no repercussions.
You won't get in any trouble so you can loot at will.
The Witcher does not have a crime system (i.e. stealing), so you can loot without any repercussions.
