Notes[]
- Without any stance equipped, the Dark Split-Sword is used as a Heavy Blade weapon by default.
Tips[]
- 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[]
- 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.
- On the Release of Update: Lunaro (2016-06-15) 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.
