Let's see: damage to creatures on the inside goes from 55hp to 78hp. That's probably ok if we make these otherwise tough enough.![]()
Very big? It's a 200 ft cylinder, so comparing to an 80-ft-long purple worm suggests something like a semi-standard 30 ft space and 20 ft reach. Except this thing is supposed to be mostly rock-hard, so we could go for a nonstandard space. I guess I'd go for the 30 ft/20 ft option, just because we can't give it a 10 ft by 200 ft space or whatever, but I might not object to 60 ft/30 ft or something.
Zaratan is 80 ft./40 ft.
I'm fine with 60 ft., though.
60 ft space and 30 ft reach?
