my god that would be agron's #1 most frustrating thing ever: punching something (generally a favoured approach to all problems) but nothing actually breaking. castus is doomed to forever piss agron off no matter what he does even if it's just taking a punch and not having the decency to bleed a bit

GOD NASIR you already have your work cut out

and hm gannicus would probably need invulnerability too. mostly for all that booze. he'd need a super liver, at least.
