This spell can only be cast while you are standing on earth or stone. The spell causes a glowing ring of positive energy to trace around your feat and slowing crawl up your body without ever touching your body. As it rises during the casting, the ring crystallizes the earth beneath you and pulls that crystal sheath over your body. At the end of casting, you are coated in a translucent and flexible skin of quartz. This sheath grants you damage reduction 10/adamantine but incurs a -2 penalty to Spot and Search checks, ranged touch attacks, or any skill checks reliant on clarity of vision. Once the sheath has absorbed a number of hit points of damage equal to 5 x your caster level, it crumbles to glittering dust.

Material Component: 200gp of diamond dust sprinkled on your feet.
