The mace may also be used for ranged combat against "good" NPCs, such as Hobbits, Ents, Gondor soldiers, High Elves, and even Dunlendings. This means that it will cause no damage to NPCs such as Orcs, Wargs, Trolls, Mirkwood spiders, Mordor spiders, and Southrons. All animals can be harmed by this attack (horses, rabbits, birds, etc.). To activate this ranged attack, hold the weapon in your hand and hold right click for 3 seconds. The attack is executed as a ring of dark ashes spreads out from around you, hurting all possible NPCs in your vicinity.
The mace was used by Sauron until his removal; the mace stayed in the mod.
