Crest of Unity + Elemental Starfield

Casual player here slowly leveling a Runemaster, but I love theory crafting and I’m trying to plan ahead. Does anyone know off hand (or have the ability to test) if Elemental Starfield will proc 3 elemental novas when wearing Crest of Unity. From what I’ve read this helm has a ton of non-obvious interactions and side effects.

Elemental Starfield description:

Whenever you cast Runic Invocation, you also cast up to one of each type of Elemental Nova that you can cast directly. Each unique Rune you have when casting Runic Invocation represents different Elemental Nova. These Novas are cast with a 0.3 second interval. This effect consumes mana equal to Elemental Nova’s mana cost.

I’m aiming for a non-frost claw based elemental nova build and I’m hoping to get an idea if Crest of Unity is worth consideration

In theory it should cast 3 tri-element novas. What would be happening is this:
You cast invocation, Elemental starfield triggers and will cast one nova per unique rune. Each one that you cast (fire, cold, lightning) will then get converted to a tri-element due to Crest of Unity.

The key point is that the trigger means that you cast it. It’s procced (so it wouldn’t trigger on things that specify “direct cast”) but it acts the same as you casting it manually. So it would be like you trying to manually cast a fire nova and the Crest of Unity turning it into a tri-element nova regardless.

Hope that helps.

Hey, the important part about Starfield is having the different elemetnal novas unlocked. Crest has nothing to do with it, its simpyl replaces any nova with the tri ele nova.

So you need to have ele novm specced and enabled all 3 nova types.

I just made 100% sure and tested it real quick ingame and can confirm it behaves as I expected.

As long as you have Ele Nova specced and chose all 3 starter nodes that unlock the different ele nova types it will work.

Elemental Starfield then will cast 3 Tri Ele nova in 0.3 intervals

Thanks! That absolutely helps.

In the build planner I had noticed that the helm “Disables the possibility of [Elemental Nova] being Lightning Nova, Ice Nova, or Fire Nova, regardless of its tree.” As a result I wasn’t sure if this would cause the runic invocation proc to be prevented given that they would be “Tri-Elemental” novas rather than the individual elements.

Heck yeah! Thank you

Yeah, the wording is a bit weird, but the meaning behind it is “preventing” a single element nova, meaning they will all be tri-element ones. I’m guessing “transform” or, even better, “force” would be more accurate.
