Pierce Damage or Piercing Damage is a type of damage. When attacking with a Sword, Spear or Bow, and a few unique Maces, a percentage of the weapon's regular Physical Damage is converted to and dealt as pierce damage. Blade Traps, Bolt Traps, and some monster-specific attacks deal pierce damage as well. Pierce Damage ignores the target's armor and it can be reduced by Pierce Resistance.
