Notes[]
- Explosions have a radial falloff of ~90%
- Explosions have a 20% chance to proc
Heat status. - Residual Arcanes can only have two active puddles at a time. For example; creating two puddles with a primary kitgun will prevent both your primary and secondary kitgun from creating any until the first two expire.
- Will deal heat explosions that do not add or combine with weapon elemental effects, retaining heat damage on explosions.
Trivia[]
- The Orokin Writing on the Residual Boils' image roughly translates to "Lesions", an inconsistency shared with Residual Malodor. It is possible that Lesions was an earlier name of the Enhancement used during development.

Patch History[]
Hotfix 35.5.6 (2024-04-10)
- Fixed Residual Arcanes not triggering while riding Merulina.
Hotfix 32.0.9 (2022-10-05)
- Fixed damage types from equipped weapons applying to Mag’s Shards while she is standing in a zone created by Residual Arcanes.
- The Arcane effects apply only to weapons, her Shards will only apply Slash damage as intended while in these zones.
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.
- Residual Boils*
On Kitgun Kill: 20% (was 5%) chance to spawn volatile hives for 3s/12s that explode when enemies approach for 80 (was 20) Heat Damage in 10m (was 2.5m). Standing in the area applies Heat Damage type to Theorem Arcanes.
*As a bonus for the four Residual Arcanes above, we’ve added some extra improvements - all four have had their buff radius increased to 9m, and each now has a 20% chance to proc their status type on all damage instances!

Hotfix 29.5.6 (2020-12-01)
