I need to figure out what category my Tinker dude falls under since that's the class he'll associate with guns.

Probably be ironic if his main weapons don't line up with that. Spider-limbed Tinker will be fun to play as if it turns out that way. Might go for a second... might...

I would guess it'd be some sort of cross-classing of rogue and tinker (if that is a thing permitted by the GM)?
