Bounding Hammer (Feat)

You throw a hammer repeatedly at a foe, making a loop of attacks with devastating results.

Prerequisites: Level 11, <Proficient with Club, Light Hammer, or Mage's Rod>

Benefit: Each time you successfully attack the same creature with a thrown Club or Light Hammer, or in melee with a Club, Light Hammer, or Mage's Rod, (which includes any Magic Rods), after the first time in an encounter, you gain +1d4 of bonus damage. This damage bonus continues to stack with every successful attack you make against the same foe within the same encounter.

The maximum bonus on each attack is a number of d4's equal to the maximum number of attacks your BAB grants you during a full attack action with either hand. You gain no bonus damage on the first hit, only on the second and later hits on the same opponent. This bonus damage is inflicted as the same damage type as is inflicted by the base weapon, and adds to that damage for purposes of overcoming DR. If the base weapon has more than one type of damage, the wielder may chose which type to bolster with this bonus damage each round.

This bonus damage applies to all attacks made by attacking as above at the same target, including bonus attacks or attacks of opportunity. As long as you continue to only attack the same foe, the bonus dice persist until the end of the encounter, or until the foe is slain (whichever occurs first). If you change targets, the bonus damage on the target you left is lost. You cannot ever build up bonus dice against more than one target at a time.

This bonus damage is considered precision damage and is not multiplied on a critical hit.

Note: If your light hammer or club does not have the returning property (gained for free when it has at least a +1 enhancement bonus), this feat will be very difficult to use.
