Temporal Artillery + Temporal Erosion is very strong! :D
I'm currently rocking 3 tau reds on Duration, a non-tau purple on [Equilibrium], and a tau yellow on Casting Speed! (You can use whatever suits you!)
Even if you don't use the augments on this build, [Equilibrium] (the mod and the purple shard buff) are insanely good on [Protea], because her Dispensary drops enhanced Health Orbs that heal 100 HP rather than 25, which is much stronger than the Energy Orbs it drops which only give 25 Energy.
This build is quite spammy, but you can get out of situations where your anchor is forcing you into one spot by holding the ability cast button to disable it without rewinding!
If you want your armor stripping to go faster, I recommend building up [Protea]'s passive strength buff before casting her Temporal Anchor, and then immediately casting her [Blaze] Artillery.
During your Temporal Anchor, I recommend spamming your Grenade Fans to charge up [Protea]'s passive to place enhanced Shield Satellites or Dispensaries! (The extra strength can go a long way for both.)
If you want to guarantee you'll have enough energy at the start of a mission, you should make sure the first ability you cast is a Dispensary!
SWAPPABLE MODS
Regular Intensify and maybe even Precision Intensify (haven't tested it) would work if you don't have/can't use [Umbral Intensify].
Regular [Flow] would work if you don't have [Primed Flow].
[Adaptation] or [Rolling Guard] would work if you don't have [Health Conversion].
[Growing Power] is not required but the extra strength is nice.
[Archon Vitality] is a huge buff to your [Blaze] Artillery DPS, but if you don't have it you can always swap it for another strength mod or another survivability mod like [Vitality].
I hope this build and my advice is helpful! If you want to do anything differently, don't be afraid to! :D
