I'm a new player so this is mostly just a wishlist for myself of what I want to get in which slots. There's a lot of stuff that I avoided putting in because I don't know how they work yet, like arcanes, primed mods, etc.
See other builds made by people who actually know what they're doing for ones that are more suited to difficult content.

Ideas for spells to take via Helminth:
Fire Blast ([Ember])
Pillage ([Hildryn])
Shock ([Volt])
