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.
Patch History[]
Update 31.6 (2022-06-09)
- ARCANE STAT CHANGES PER RANK
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.
