Blood Armor

Standard Action | V, S | Personal | You
1 Minute/level
Your blood becomes as hard as iron upon contact with air. Each time you take at least 5 points of piercing or slashing damage, your
armor gains a +1 enhancement bonus to your
AC (maximum +5). This enhancement bonus stacks with itself, but not existing enhancement bonuses. This spell has no effect while underwater or in environments that lack air.
