You're covered in tiny nuns. Every time you would be hit by a spell or weapon, these tiny nuns selflessly throw themselves between you and the effect. You have as many nuns as you have HPs. You also carry extra nuns in a magic bag, and use of a healing surge entails nothing more complicated than pouring some nuns onto you. If you run out of nuns and go into anti-nun territory, that's a sign of the universe disfavoring you and pouring tiny satanic nuns onto you through an invisible fissure in reality. It takes an act of divine favor to throw off these anti-nuns and return to positive nun status.
These aren't very good nuns, because they breed like bunnies and an overnight rest will restore you to full nun status.
