Bigby's Crushing Hand – Spell
The crushing hand can also interpose itself as Bigby's interposing hand does, or it can bull rush an opponent as Bigby's forceful hand does, but at a +18 bonus. Directing the spell to a new target is a move action. Clerics who cast this spell name it for their deities—St. Cuthbert's crushing hand, for example.
