Entomber

Weapon · 111000 gp · Weight 0

Whenever the wielder of this +4 warhammer successfully hits an enemy with a charge attack, the enemy must pass a Fortitude saving throw (DC 33) or be entrapped in stone until the end of the fight. While under this effect the enemy becomes vulnerable to bludgeoning damage as well as slowed down. If this warhammer confirms a critical hit against an affected enemy, all enemies in a 30-foot area should pass the same check or be under the same effect.
