Blood Mantle

This spell enshrouds the priest in a cloak of swirling blood-red droplets. This magical mantle seems to shimmer and swirl, even if there is no wind present, and moves to interpose itself between any attack and the priest. Any weapon used to strike the priest seems to impact an iron wall as the ferrous droplets momentarily coagulate to form a bulwark against the imminent attack.
While protected by a blood mantle, the spellcaster has a +3 bonus to his or her Armor Class and a +3 saving throw bonus against fire and cold (magical and nonmagical). Blood mantle are particularly conductive to electrical attacks, however, and bearers of the blood mantles receive a -3 penalty to their saving throws vs. lightning and electricity (magical and nonmagical) while protected by this spell.
In addition, the caster can remove the blood mantle and hurl it up to 10 feet away to form a 10-foot-square curtain of droplets. Once it reaches its desired position and configuration (mentally selected by the spellcaster as the blood mantle is hurled), the curtain is immovable until the spell expires. In this form, the blood mantle acts as a Wall of Iron identical in effect to the barrier created by the 5th-level wizard spell except that it is impervious to the attacks of rust monsters and similar corrosion attacks, is much smaller in area of effect, and is of limited duration.
