Reave is there for consistent health [Regen], and shields I guess. [Brief Respite] for shield gating and [Augur Reach] for the same and I didn't know what else to put there. By my testing, high efficiency is better than high energy pool, probably because energy gained doesn't scale with total energy, so max efficiency. [Exothermic] is a big help with energy as well, make sure to run around and get those orbs, which will synergize with energize, further testing required to see if energize is truly necessary. This build is wellspring independent. [Adaptation] and [Umbral Vitality] mean you have loads of damage reduction, need to test if [Adaptation] makes much of a difference. [Stretch] and [Umbral Intensify] make abilities better, duration is not very important so 60% is fine. [Primed Sure Footed] is really important with the new energy leech eximi, and I use [Kuva Tonkor] with [Ember] to nuke armour stripped enemies.
