The Armadyl godsword is one of the four legendary godswords that was fought over during the God Wars. Requiring 75 Attack to wield, it is created by attaching an Armadyl hilt to a completed godsword blade, which has no requirements and can be done by any player.
The Armadyl godsword has either a special attack or a passive effect, of which only one can be active at a time. The player can switch between the two by using the godsword on the altar in the God Wars Dungeon in the room where Kree'arra and his minions are, however entering Armadyl's Eyrie requires 70 Ranged.
The special attack is called Armadyl's Judgement, which deals up to 250% damage and uses 50% adrenaline/special attack bar. However, the description has not been updated since the Combat beta's release in January 2014 and this special attack's damage has been tweaked many times since. Test results (critical hit of 5427 at an ability damage of 1460 and no other boosts) suggests the special actually deals up to 372% damage. Under Legacy Mode, the damage is slightly higher to compensate for the larger time interval between attacks.
The passive effect takes effect 25% of the time; when it does, it raises the wielder's Attack and Strength levels by 1 each time, for up to 10% of the wielder's levels. However this passive is fairly unpopular as the boost does not stack with potions and so does not provide any damage boosts, unlike the special attack.
