Casting Time: 1 standard action
Components: V, S, M (granite and diamond dust worth 250 gp)

Spell Resistance: Yes (harmless)

The warded creature gains resistance to blows, cuts, stabs, and slashes. The subject gains DR 10/adamantine. It ignores the first 10 points of damage each time it takes damage from a weapon, though an adamantine weapon bypasses the reduction. Once the spell has prevented a total of 10 points of damage per caster level (maximum 150 points), it is discharged.

Material Component

Granite and 250 gp worth of diamond dust sprinkled on the target's skin.
