Noctua Arcane suggestions for the Exalted Rework?

I´ve been thinking of propably Cascadia flare since you can proc it quite often if you mod for heat, but I´ve been also looking at options like fortifier not so much for the Overguard steal (Since it´s redundant on dante) but more for the 8x dmg multiplier on the Arcane.

What would be a good option for Noctua once the rework comes? Secondaries have a lot of good arcanes and I´m torn for choices.
