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.

Characteristics[edit | edit source]

This weapon deals DmgRadiationSmall64.png Radiation damage.



  • Innate DmgRadiationSmall64.png Radiation damage – less effective against shields
  • Tied with the SomaDualKamas.png Dual Raza for the third lowest damage of all dual swords.
  • Stance slot has Ability polarity, does not match the Conclave-only Mod TT 20px.png Dividing Blades stance.
    • Ability stance polarity is incompatible with any of the heavy blade stances.


  • Dark Split-Sword (Heavy Blade), compared to Dark Split-Sword (Dual Swords):
    • Lower base damage (96 vs. 101.9)
      • Lower DmgPunctureSmall64.png Puncture damage (32.6 vs. 49.2)
      • Lower DmgSlashSmall64.png Slash damage (21.7 vs. 24.6)
      • Higher DmgRadiationSmall64.png Radiation damage (41.7 vs. 28.1)
    • Lower attack speed (0.92 vs. 1.17)
    • Higher Block Angle (85° vs. 1°)
    • Higher block resist (50% vs. 45%)

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.

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.png Dark Sword and a DarkDagger.png 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.
  • 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.
