domain expansion: malevolent shrine

A domain expands covering 0-656 feet of area around the caster. Malevolent Shrine's guaranteed-hit ability can be made to relentlessly slash apart anything until nothing but dust remains of what has been caught in the effective range. the user must use a turn to prepare the domain, in this time the caster cannot move or defend against attacks. if the user still maintains more than 50% of their hit points by their next turn, the domain expansion occurs. the domain will be dispelled either by the caster receiving more than 50% damage, another domain being cast, or when the caster determines. targets take 8d6 damage, on a successful constitution save targets take half damage.
