Barrel Diffusion is a mod that increases the multishot of pistols. These additional rounds do not consume extra ammunition.


Rank Effect Cost
0 +20% 6
1 +40% 7
2 +60% 8
3 +80% 9
4 +100% 10
5 +120% 11


  • The additional rounds do not consume additional ammunition.
  • At rank 4 or higher, this mod guarantees that at least 2 rounds will be fired for every 1 round of ammunition expended.
  • At maximum rank, this mod grants an 100% chance to fire one additional round (2 rounds/shot) and a 20% chance to fire two additional rounds (3 rounds/shot).
    • Equipping this mod and Mod TT 20px.png Lethal Torrent simultaneously will provide 180% multishot, giving the sidearm a 100% chance to fire one additional round (2 rounds/shot) and an 80% chance to fire two additional rounds (3 rounds/shot).
    • For weapons that fire multiple pellets (i.e. a Bronco.png Bronco) the pellet count is multiplied by the multishot value.
      • A Bronco.png Bronco with a rank 5 Barrel Diffusion will fire pellets, meaning it has a 60% chance to fire 15 pellets and a 40% chance to fire 16 pellets.
  • The in-game UI will consider any possible multishot capabilities when showing total damage numbers, and does not represent single-projectile damage.
    • Total damage displayed does not represent the actual damage per shot, but the expected average damage.
  • Equipping this mod increases the status chance of a weapon indirectly. This is due to the possibility of shooting more than one projectile.
