Shield Gate : Decaying Dragon Key
By utilizing a decaying dragon key, not only does [Protea] have a strong shield gate in the form of her shield grenades, she can also use several of her abilities to give her many shield gate buffers.
With [Brief Respite] and the two augur mods, her 2nd, 3rd, and 4th ability cause her to go from 0 shield to overshields in one cast, giving her a full shield gate on command.
When you cast temporal anchor, not only do you get overshields, but when you rewind either intentionally or through death, you gain back your overshields. This allows you to recast your anchor again or [Recover] from the ragdoll animation while the shield gate is still active.
[Rolling Guard] has an extremely quick recovery with her unique dodge animation, which lets you make more use of the invincibility.
Arcane aegis gives you 12 seconds of invincibility if it procs.
Combining all of this with the increased shield gate duration from her Fan Grenade drones, and you are effectively invincible as long as you keep on your toes and make good use of the several forms of invincibility you have in your arsenal.
If you are fighting infested it is highly suggested you slot in Arcane Resistance as toxin damage goes through the vast majority of your forms of defense. Usually you slot it over aegis but if you are confident in your energy economy you can slot it over energize.
