Defensive Roll (Combat)

Prerequisite: Wisdom 13+

Benefit: Once per day, when you would be reduced in hit points in combat (from a weapon or other blow, not a spell or special ability) so that you would be staggered, unconscious or dead, you can attempt to roll with the damage. If you make a Reflex save (DC = damage dealt), you take only half the damage from the blow.

You must be aware of the attack and able to react to it in order to execute the Defensive Roll — if your Dexterity modifier to Defense is denied, you can’t roll. Since this effect normally would not allow you to make a Reflex save for half damage,
