Please like if the build and guide helped you!
General
This build focus on tankiness, while still doing damage with [Ember]'s abilities. Breach Surge sparks can be created by 3, the initial (crash) damage of 4 and it's DoT ring. Basically spread those sparks by creating meteors and DoT rings!
Don't have [Primed Sure Footed]? Use [Power Drift].
Can't fit Umbral mods? Use their regular counterparts.
Subsume ability: anything (e.g.: Roar, Eclipse). I think Breach Surge is the most effective.
Mods / Arcanes
First arcane: arcane [Guardian] for more armor and thus more damage reduction.
Second arcane: your choice.
