Using mesh as collision component instead of capsule component?

Hello,

I want to use my mesh as collision box because I want to make a sword game where if the sword hits your arm it brakes the bones and dismembers it. The problem is that the collision capsule does not adapt to the human body well, and instead I was wondering if I could use the mesh as collision component.

I have read somewhere that you could do this using a Pawn as category instead of Character, but that then I would lose all my blueprint functionality because I wouldn’t have a CharacterMovementComponent, and that I would have to use one for the pawn although it has limited functionality?

Does anybody know how would I do this transition from Character to Pawn? A tutorial or something? I’m using 5.2 so I don’t find many tutorials for this version.

What alternatives do you suggest?

Thank you.
