Stone (OA)

You can generate a stone ward, a spell-like ability to grant yourself or someone you touch damage reduction 5/— against attacks from stone weapons, creatures (such as earth elementals, gargoyles, clay golems, and stone golems), or spell effects, or against damage from falling onto earth or stone. This reduces the damage taken from such attacks by 5 each time damage is dealt. Activating this power is a standard action. The stone ward is an abjuration effect with a duration of 1 minute + 1 minute/level that is usable once per day.
