Blood Mantle

This spell enshrouds the user in a cloak of swirling blood-red droplets. This magical mantle acts as a barrier to interpose between an attack and yourself while the mantle is active the spellcaster has a +3 bonus to their AC and a +3 saving throw bonus against fire and cold effects. The spellcaster suffers from a -3 to saving throws against lightning effects. 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 ends. In this form, the blood mantle acts as a wall of iron.
