Armadyl battlestaff

Not to be confused with the Staff of Armadyl.

The Armadyl battlestaff is a two-handed Magic staff that requires 77 Magic and 40 Attack to wield. It is created by attaching an orb of armadyl to a regular battlestaff, which requires 77 Crafting and grants 150 Crafting experience.

In addition to providing the second-best hit bonus of all staves, behind only the chaotic staff, the Armadyl battlestaff acts as a staff of air, in that it provides unlimited air runes when wielded. This allows players to cast air spells, such as Air Surge, for free, as well as reducing the cost of all other standard elemental spells and Gale spells. This potentially makes the Armadyl battlestaff a superior choice for common combat activities such as Slayer training.

Wielding the staff also provides a damage boost to the Storm of Armadyl spell.

Lore
As a weapon of the god Armadyl, the Staff of Armadyl was one of the most powerful artefacts to ever exist in the world of Gielinor. It was instrumental in the overthrow of Zaros by the then-Mahjarrat Zamorak, as well as his successive ascension to godhood. An entire organization, the Guardians of Armadyl, was formed in order to guard the staff in its resting place, the Temple of Ikov. However, it was eventually stolen by the Mahjarrat Lucien, who wielded it in order to advance his goals of conquering the world and, much as Zamorak had done, attaining godhood. The staff's power was so great that Lucien, who was perceived by the other Mahjarrat as among the weakest of their kind, quickly became one of the strongest beings in the world, unmatched in combat and able to defeat many of the world's heroes at once. Once Lucien obtained the Stone of Jas as well as the Staff of Armadyl, his overwhelming victory seemed inevitable.

However, during the events of Ritual of the Mahjarrat, Lucien was defeated by a trio of dragonkin, who had become enraged by Lucien's misuse of the Stone of Jas. During the battle, the Staff of Armadyl was broken when Sakirth the dragonkin struck Lucien with it, shattering the staff's head. The fragments of the orb that once adorned the staff's head were later recovered by glacors, creatures of ice that had been summoned by Lucien. The Armadyl battlestaff may be created by collecting these shards and combining them into an orb of armadyl, and attaching to a battlestaff. Although the Armadyl battlestaff carries but a small fraction of the power of its predecessor, the Staff of Armadyl, it is nonetheless a formidable weapon in the hands of a human adventurer.

Trivia

 * Despite the fact that Storm of Armadyl, the companion spell to the Armadyl battlestaff, requires completion of Ritual of the Mahjarrat to cast, the staff does not require completion of the quest to wield.
 * Prior to the Evolution of Combat, the Armadyl battlestaff increased the casting speed of Storm of Armadyl from 3 seconds to 2.4 seconds. This made it one of only two ways to cast spells faster than the standard rate, the other being the Blitzer class of a ring of kinship. However, the latter was a randomly occurring effect (unless the ring was fully upgraded) and only available in Daemonheim.
 * There is currently a stretching glitch with the top part of the Armadyl Battlestaff.
