When using “Luminaire” node in Elemental Nova, nodes such as “Elemental Tranquility” no longer apply ailments at all. Nodes Like “Glyph of Winter” and “Immolation” still work, presumably since they proc regardless of Nova type.
Additionally, Sorcerer Passive “Dragon Breath” also gives no ailment for channeled elemental Nova.
If “Luminaire” node is not used, Elemental Nova again applies ailments from these nodes
Depending on the application of ailments (e.g. ignite on hit), channelled skills sometimes only apply ailments when the channel is first started - i.e. on the first “hit” - subsequent hits then dont apply because its now channelled and dont count as separate hits/applications of the skill.
Could this be what you are experiencing?
(note things like Glyph of Winter and Immolation would work because they are part of the skill)
Ok. Have been doing some testing to see whats happening.
With a sorcerer - wearing just a helm with +3 Elemental Nova for testing - no other gear or idols. By default. No passives that increase or enable any ailments of any kind.
Elemental Nova setup with one point in each Nova type, 3 in Elemental Expance.
Then 6 in Elemental Tranquility and 1 in Luminaire when activated.
With Elemental Tranquility. I get stacks of Shock & Fire ailments (freeze doesnt show icon if I recall).
With Luminaire & Elemental Traquility. I get no ailments so it doesnt work.
With Luminaire & gear with ailment on hit (e.g. ignite shock on hit on wands), I get multiple stacks of ailments even tho its channelled.
With Luminare & Passives - Pyromancer and Ceraunomancer works.
Cannot tell if Cryomancer works.
With Luminare & Passives - Dragons Breath does NOT work
I can confirm the OPs bug for both Elemental Nova and Dragon Breath.
Gear (on hit ailments) works even though the skill is channelled.
Certain passives do work with Luminaire enabled.
Did that. Tested multiple times starting and stopping channelling within the 4s limit
Even tested it by firing off unspec’d fireball before channelling Nova just to make 100%
Character sheet ailment chance doesnt change either.
At no time does Elemental Nova apply Dragon Breath Ailments.
I suspect that gear that specifies that it only applies ailments for specific elements, like chance to ignite with fire skills, would also not work.
What you’ve tested here seems consistent with my testing. Ailments that require it to be a fire, lightning, or cold skill do nothing. General ailments that apply on any cast will work.
