1. Do the bonus physical stress boxes from high endurance, inhuman toughness and hulking all stack?
So a creature with Supernatural toughness, hulking, and good endurance would have:
4 + 4 + 2 = 10 boxes of physical stress, 4 of which do not count against the catch?
2. Does a weapon rating stack with the bonus shifts of damage granted by inhuman strength?
3. Would a Nian's weakness to fireworks (As listed on the creature's wiki page) count as a +3 or +4 catch?
I know the last one is ST fiat, but I would welcome opinions on it nonetheless.
Thank you.
