  • Directly reduces ammo cost by a percentage, while active. At rank 5 no ammo will be consumed.
    • After being activated by the secondary, the buff also works on primary weapons.
    • Getting another proc does not refresh the timer. The current instance of Arcane Pistoleer must run out before another can be started.
  • In order for the arcane to activate enemy must be killed with direct damage, Gas or Electric status effects. Other damage over time effects will not trigger the buff.
  • Alt-fire modes that shoot all remaining bullets in an automatic burst (Cyanex Cyanex, Nagantaka Nagantaka, or Pandero Pandero) shoot the current number of bullets left in the magazine while conserving them, allowing for an ammo-efficient, repeated use of these modes.
    • Azima Azima alt-fire still consumes the entire magazine as normal, but the turrets themselves benefit from partial ammo efficiency, expending their ammo more slowly and therefore lasting much longer. However, 100% ammo efficiency does not benefit turrets in any way and they will last their normal duration.
  • Is also capable of being toggled by pistol Exalted Weapons like the DexPixia Dex Pixia.


  • Can greatly improve the performance of weapons that otherwise have low magazine size like Akbronco Akbronco (AkbroncoPrime Prime) or TwinRogga Twin Rogga.
  • Synergizes well with PyranaPrime Pyrana Prime's passive, allowing the wielder to make more use of the fire rate/akimbo buff without sacrificing the buff's duration to reloads.

Patch History[]

Update 31.6 (2022-06-09)


We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.

Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.
