[Sevagoth] BUILD FOR ENERGY HUNGERS,
[Sevagoth], In my opininion, is a great frame for survival missions, Especially steel path ones. You dont need enery mods since [Hunter Adrenaline] and Arcane Energize will give you Infinite energy [Regen]. You also dont neeed duration since you will be using for Gloom (which scales with range and power mods) + your weapon of choice most of the time. [Adaptation] and Arcane [Guardian] for extra Thicc skin so you can take the hit. You can swap [Transient Fortitude] for [Blind Rage] if you want more slow on Gloom.
Have a great time in Game Tennos!
