  • Additively stacks with mods that increase fire rate (e.g. Mod TT 20px.png Speed Trigger).
    • Does not double its bonus for bows
  • Works with most primary weapons, including snipers & launchers, but not with shotguns.
    • Can be triggered with all weapons, including melee.
    • The arcane also works with the ArtemisBowWeapon.png Artemis Bow, from IvaraIcon272.png Ivara (Ivara PrimeIcon272.png Prime), due to the fact that it is the only primary Exalted Weapon.


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.
