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.

Notes[edit | edit source]

  • Without any stance equipped, the Dark Split-Sword is used as a Heavy Blade weapon by default.

Tips[edit | edit source]

  • 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.

Trivia[edit | edit source]

  • 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 DarkSword.pngDark Sword and a DarkDagger.pngDark 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.
  • On the Release of Update: Lunaro on PC, PC Gamer offered a limited time promo code for the Dulus weapon skin, which is essentially a stretched out PC Gamer logo on the sword.
