Cloak Against All Peril

Cloak against all peril creates an invisible energy shield to absorb damage from all attacks against the caster. The cloak absorbs 3d4 points of damage plus 1 point per experience level of the caster. It can deflect damage from a single attack or from a number of successive attacks, although the spell has a maximum duration of only 1 round per level of the caster. The cloak dissipates when this duration lapses or when it has absorbed all the damage it can. This spell cannot heal damage inflicted before casting.
