Here is my Heat staff ! No [Primed Pressure Point] because [Condition Overload] is more than enough and dminishing returns won't give you that much on PPP anyway (40% instead of the full 165%). And reach is good on staves. Use [Spring-Loaded Blade] if you don't have [Primed Reach] ! That's also why I don't use Arcane [Fury] on the main frame build.

You can get around the umbral forma by using two formas on [Organ Shatter] and [Volcanic Edge]. Also you are free to go for Viral if you want to, and free to stay on corrosive if you feel like it, playing Nourish whatsoever.
