Dual Spears

 Dual Spears (二槍刀流, Niyaritōryū) is a unique skill in Sword Art Online that is only seen in the Chaos Labyrinth and Project Dreamscape arcs of Yasuda Izumi's fanfiction, Sword Art Online: Annulment. In ALfheim Online, the setting for the final two arcs of Annulment, this formerly unique skill becomes an extra skill.

Overview
In the Ulster Cycle of Irish folklore, a hero by the name of Cú Chulainn wielded a spear called the Gáe Bolg. He received it from his teacher Scáthach who used two spears in her fighting style. decided to play on this and gain a few laughs by instigating it into both SAO and ALO.

The Dual Spears skill gives a 2x boost to attack power, skill activation speed and damage. It also increases the agility stat and the owner's ability to jump.

Acquisition
The prerequisites to obtain this skill is to be female, have a two-handed spear skill proficiency of at least 800, and to have excellent leadership skills (e.g. commander of the number one guild). Professor Kayaba must have been drunk when he included these prerequisites.
