Magic Weapon Abilities - Bloodthirsty
A bloodthirsty weapon grants its wielder a +2 morale bonus on attack rolls so long as the blade is sated. To keep it sated, the wielder must use the weapon to kill a creature of at least 4 HD every 24 hours. When this blood price goes unpaid, the bonus on attack rolls is replaced by a -2 penalty. The bonus replaces the penalty again as soon as the wielder has slaked the weapon's need to slay.
