You use a file to sharpen a skeleton's finger bones, drive spikes and blades through a zombie's forearms, or otherwise improve your undead creation's ability to deal damage in melee.
Benefit: An undead creature created with this feat gains a +1 bonus on damage rolls when attacking with its natural weapons. A zombie gains this bonus for its slam attack, while a skeleton gains the benefit for its claw attacks. A zombie's slam modified in this way now deals slashing damage as well as bludgeoning damage. The skeleton's claws still deal piercing and slashing damage. See the Monster Manual for details on natural weapons and damage types.
Prior to animation, you must spend 5 gp on bladed weapons to add to each undead created in this manner. It takes one day to modify each skeleton or corpse. For the purpose of control, treat the resulting creature as having 1more Hit Die than it actually does.
