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.
