Use as a devastating heavy sword or apply a Dual Melee stance and split the weapon into two ferocious blades.
The Dark Split-Sword is a melee weapon with the unique ability to change weapon type depending on the Stance mod with which it is equipped: a double-bladed greatsword when equipped with Heavy Blade stances, or wielded as two separate blades when using Dual Sword stances.
Without any stance equipped, the Dark Split-Sword is used as a Heavy Blade weapon by default.
Heavy Blade and Dual Sword stances do not share any polarities, meaning players are forced to commit to either one of the two weapon types.
Alternatively, players can remove the stance slot's polarity with a Forma at the cost of capacity points.
Moreover, players can use a Stance Forma in order to add either Heavy Blade or Dual Sword stance mods with no consequences.
The Dark Split-Sword is the first melee weapon capable of using two different types of Stance mods, in this case Heavy Blade and Dual Sword stances, giving it the ability to use a total of 6 individual Stance mods.
The Dark Split-Sword is made up of a Dark Sword and a Dark Dagger. This can be seen when equipping a dual swords stance.
The Dark Split-Sword is the first weapon from the Tenno Lab to require Mutagen Masses to craft.
