400% Ability Stength for that 100% armor/shield strip can be achieved with 5 crimson archon shards or 3 tauforged + 1 normal crimson archon shard. Or, with 5 tauforged, you can replace [Amar's Hatred] or [Augur Secrets] or [Power Drift] with a mod of your choice. 400% ability strength also makes your [Balefire Charger] crazy powerful.

[Blazing Pillage] is replaceable, you can use an ability range mod or [Natural Talent] there.

Use whatever aura and helminth ability that applies to your loadout and how you play.

I recommend you use a robotic companion so that you can use [Guardian], which replenishes 100% of your shields when it runs out.
