Body Blades

This spell causes many dagger-like blades to sprout from all surfaces of the caster's body. They appear to be metallic but are not actually metal (and are therefore unaffected by heat metal spells, magnetic attraction, and the like). They materialize through or out of any armor, gear, or clothing worn, but don't obscure the senses or affect Dexterity. Even if they grow from the face, vision is unimpaired; if they grow from the hands, spell-casting and the like is unimpeded; and if “sticking” into adjacent body parts, they do no damage and act as if they were mere illusions.) The blades never harm gear worn or carried by the caster.

To others, the spiny forest of blades augments the caster's Armor Class by 2 points, and inflicts harm as follows: If the caster charges, the blades impale for 1d4+2 points of damage. If the caster hugs, overbears, or drives a foe against a solid surface. such as a wall, damage is doubled (a successful attack roll, without bonuses, is required to manage such maneuvers).

If a caster with body blades is caught in a constricting situation (such as a closing door or compressing, moving wall), the blades halt the movement, preventing damage, though the caster will be wedged in tightly.

The material components are two shards of metal that each possess at least one sharp edge or point (bladed weapons can be used), and one shard of bone with at least on sharp edge or point (from any source).
