Stone Biology (3.5e Maneuver)

''She's hardening parts of her body, its like diamond! I can't cut through!''

As an immediate action you petrify yourself, briefly becoming an object with hardness 8. It lasts only to counter a single attack, but you are immune to any effect which does not work on objects. It takes a moment for your hard stone shell to flake off completely though, and you are staggered until the end of your next turn.
