When the wizard casts this spell, he becomes completely immune to physical attacks by creatures of up to and including 6 levels or Hit Dice. For every two levels beyond twelfth the caster attains, the level or Hit Dice limit augments by one: 7 HD at fourteenth level, 8 HD at sixteenth level, 9 HD at eighteenth level, etc. The immunity includes attacks from persons, such as punching.
The material component is the claw of a creature having suitable Hit Dice; 6 at twelfth level, 7 at fourteenth, etc. A lesser one can be used, with analogous decrease to the spell's power.
