CODEX

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

This weapon deals primarily  Puncture damage in dual sword form and primarily  Radiation damage in heavy blade form.

Advantages:

• Innate  Radiation damage – effective against Alloy Armor, Robotics, and Infested Sinew.
• High  Puncture and good  Slash damage – effective against armor and health.
• Dual Sword:
  • High critical chance and critical multiplier.
  • Good status chance.
  • Fast attack speed.
• Heavy Blade:
  • Very high status chance.
• Stance slot has polarity, matches  Swirling Tiger stance.
• Innate polarity.

Disadvantages:

• Innate  Radiation damage – less effective against Shielded, Infested, and Fossilized.
• No  Impact damage – less effective against shields.
  • Damage cannot be increased with  Impact mods.
• Heavy Blade:
  • Low critical chance.
  • Below average attack speed.
  • stance polarity is incompatible with any of the heavy blade stances.

Comparisons:

• Dark Split-Sword (Heavy Blade) (Normal), compared to Dark Split-Sword (Dual Swords) (Normal):
  • Higher base damage (230 vs. 116)
    • Higher  Puncture damage (78 vs. 56)
    • Higher  Slash damage (52 vs. 28)
    • Higher  Radiation damage (100 vs. 32)
  • Lower critical chance (15% vs. 25%)
  • Lower critical multiplier (2x vs. 2.5x)

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.
