A Mirrorsword is a type of Eldar Power Sword employed by a Howling Banshee Exarch. Two Mirrorswords are commonly employed by those Howling Banshee Exarchs who have mastered a deadly ambidextrous form of melee combat that uses the paired blades of two matching Power Swords. Mirrorswords allow for a greater number of blows to be made by the wielder in melee combat, compared to other Eldar warriors who also wield dual close combat weapons.
