I like taking on whole fields full of them with plenty of shotgun shells, mixed with cacodemons and other assorted hell spawn.
A_TroopAttack in p_enemy.c gives clawing damage as 3-24.
mobjinfo in info.c says that projectile damage always has "eight-sided dice", and PIT_CheckThing in p_map.c says that there are three dice for the Imp, which implies 3-24 points of damage for the fireball.
Did I miss anything? Ryan W 14:11, 6 November 2006 (UTC)
