Stoneskin

At 3rd level, and every two levels thereafter, a sorcerer learns an additional spell, derived from her bloodline. These spells are in addition to the number of spells given at new levels. Stoneskin: 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 overcomes the damage reduction. Once the spell has prevented a total of 10 points of damage per caster level (maximum 150 points), it is discharged.
