Notes
- Additively stacks with mods that increase fire rate (e.g.
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 Artemis Bow, from Ivara ( Prime), due to the fact that it is the only primary Exalted Weapon.
Trivia
- This arcane was originally dropped in The Law of Retribution and its associated Nightmare Mode. Following Update 22.14 (2018-03-01), all Trial missions were retired from the game and the arcane drops were moved to the Eidolons instead.
