Dual Daggers

Dual Daggers (二短刀流, Nitantōryū) is a unique skill in Sword Art Online that is only seen in the Chaos Labyrinth and the Dreamscape Project arcs. In the ALfheim Online virtual world, this is an Extra Skill, obtainable by anyone who meets its prerequisites.

Overview
An assassin's weapon of choice is of course, the trusty dagger. Their dagger could also serve as their lifeline. Some assassins carry two, just in case. Others incorporate the use of two daggers into their assassination style. Basing it off of this, created this unique skill. In SAO, the skill is unique. One person owns it and that is Illyasviel, the Youthful Prince of the Short Sword. However, in ALO, the skill becomes an Extra Skill that can be obtained by anyone who meets prerequisites.

The Dual Daggers skill gives a 2x boost to agility, attack power, and sword skill activation speed. It also reduces SP usage by 50%, the largest SP usage cut. It is not an understatement to say that sword skills in this category can be spammed.

Acquisition
Professor Akihiko set the prerequisites of obtaining this unique skill (Extra Skill in ALO) to 950+ one-handed dagger skill, 900+ Hiding skill and 900+ Sprint skill along with a high AGI (agility) stat.
