An endurance build focused around shield gating for surviving, using I-frames from [Rolling Guard] and her 4 to buy time for shield [Regen] via [Brief Respite]. And using stacking on her 2 for damaging enemies.

in this build you will want to be using naramon to maintain combo for a 3.75x damage multiplier to increase stacking speed.

you will want to always have a spectrorage placed down for energy [Regen], but its also a good ability to use to fuel [Brief Respite] so don't be worried about recasting it early.

a viral+heat status hose will be great at increasing your effectiveness against heavily armoured units.

for mod changes you can switch [Augur Secrets] for another duration mod if you prefer but other than that there isn't much flexibility.

As for heminth, there isnt really a good option for infusions, as you NEED your 1,2 and 4 and your 3 is amazing utility for regaining energy to use for [Brief Respite], you COULD infuse eclipse for faster stacking in place of spectro and run a duration mod instead of the augment, however you would most likely have to give up narmon for zenurik to make energy more reliable, which would make it almost impossible to maintain combo without a combo duration mod. but if you were really committed you could run 5/6 on the augur set for 200% energy to shields and drop breif respite for [Swift Momentum].
