Rock Catching

The creature can catch rocks (or projectiles of similar shape) of up to their own size category. Once per round, a creature that would normally be hit by a rock can make a Reflex save to catch it as a free action. The DC for catching of a rock of their own size is 25. Each size category smaller reduces the DC by 5, thus the save DC for a Large hill giant trying to catch a Small rock would be 15. (If the projectile provides a magical bonus on attack rolls, the DC increases by that amount.) The creature must be aware of the attack in order to make a rock catching attempt.
