The ancient mace is a weapon that can be acquired during the Another Slice of H.A.M. quest. Although tradeable, it cannot be wielded until after a certain point in the quest; attempting to do so results in the message You must have received that mace in Another Slice of H.A.M in order to wield it.
The ancient mace has stats in between those of a black mace and mithril mace and requires level 15 Attack and level 25 Prayer to wield. In addition, it can be equipped to be protected against the Bandosian followers in the God Wars Dungeon.
If lost, it can be retrieved from the goblin archaeologist Tegdak for 1,000 coins, north-east of the Dorgesh-Kaan marketplace.
A player wielding an ancient mace.
A player performing the ancient mace's special attack, Favour of the War God.
The ancient mace has a special attack, Favour of the War God, requiring 100% Special Attack energy, that hits through Protect from Melee and drains the Prayer points of the opponent by 100% of the amount hit and recharges the user's prayer points by the same amount. This can raise your current Prayer points to above your maximum Prayer level, up to the amount of damage inflicted by the attack. The special attack will restore prayer even if used against a target that has immunity to conventional weaponry such as Turoths and Kurasks.
In order to maximise the amount of prayer points restored, activating a melee-boosting prayer (such as Piety) before using the special attack is advised.
It can be used to attack a combat dummy (or undead combat dummy) in a player-owned house Combat Room in order to maximise the Prayer surplus effect, as hitting the dummy will always result in the player's max hit. In addition, it is a useful tool for restoring prayer while in the Nightmare Zone after activating a power surge power-up, which gives the player infinite special attack power.
- Players cannot cast High or Low Level Alchemy on the Ancient mace; doing so results in the message: This ancient artifact resists your magic. However, players can sell the mace to general stores for 400 coins.
- Despite being described as "ancient", the mace is not associated with Zaros, whom most ancient items are affiliated with.
