The void knight mace can be bought from a Void Knight for 250 commendation points, although a player must have 42 Attack, Strength, Defence, Hitpoints, Ranged, and Magic, along with 22 Prayer. The mace can also be used to autocast the Claws of Guthix, Crumble Undead, wave and surge spells. To cast Claws of Guthix, the player still must have cast the spell 100 times in the Wilderness Mage Arena.
Note that the Void knight mace does not count towards the four pieces needed for the void set effect.
This weapon is slightly better than a Rune mace, with an additional +2 for Stab, Slash, and Crush Attack; +2 Stab, Slash, Crush, Magic and Ranged Defence; +2 Strength; +2 Prayer; and +8 Magic Attack. This makes it one of the only melee weapons in game to have a positive ranged defence bonus, other than the Red topaz machete and Lunar staff, with +1, and the dragon spear and Zamorakian spear, with +5 and +13, respectively. Unlike other maces, however, it only has crushing attack styles. Alongside croziers and the 3rd age druidic staff, it has the highest Prayer bonus of all one-handed weapons.
