Yeah I'm not the best at making builds but this is the one I use and it works so yeah
Nourish is for energy [Regen], also some viral on enemies is never a bad thing
The build is incentrated around Final Stand and Passive Crit.
Other than the arcanes you need to also cound three tauforged red archon shards for 45% more power strength and two tauforged blue archon shards for 450 more shields. Along with maxed out overshields and a speargun equipped you will arrive at a stunning 200% plus passive crit with 4000 total shields or more.
Edit:
I put more duration cuz fuck efficiency
