Tw0 Fang is the tier 5 skill in Zer0's Cunning skill tree. It gives any weapon fired a chance to fire twice.


  • Double Shot Chance: +6% per level
Level 1 2 3 4 5
Double Shot +6%+12%+18%+24%+30%
Level 6 7 8 9 10 11
Double Shot +36%+42%+48%+54%+60%+66%

Can only leveled past 5 with Professional, Rogue, and Legendary Killer class mods.


  • Tw0 Fang functions somewhat similarly Mordecai's Gun Crazy skill from Borderlands, but affects all weapon types.
    • Unlike Gun Crazy, Tw0 Fang causes a two-shot burst rather than firing two shots at once. This consumes additional ammo and causes recoil as normal.
  • Shadow of the Seraphs' special effect is additive with Tw0 Fang, effectively increasing the chance that two shots will be fired by the amount listed on the relic. Notably, with a perfect level 62 or above Shadow of the Seraphs relic and an Unparalleled Professional or Rogue class mod it is possible to achieve a 100% chance of double fire with each shot.
  • Tw0 Fang's effect requires a minimum delay between shots, meaning that it will not trigger at all on weapons with too high a fire rate, roughly 10.0 or above. This includes not only weapons which have a base fire rate at or above 10.0, but also those which are boosted to or above 10.0 by skills, relics, class mods, and/or Badass Rank. Many SMGs and Assault Rifles are affected by this exclusion.[1]
