  • 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 EWArtemisBow.png Artemis Bow, from IvaraIcon272.png Ivara (Ivara PrimeIcon272.png Prime), due to the fact that it is the only primary Exalted Weapon.
