Run it with 4x blue shard for 4x150 enegry shield and a single red shard for ability strength.
The extra 10% ability strength allows you to [Reach] the extra 2% armor strip on your pillage, reaching 82% that fully strips with the 18% from [Corrosive Projection].
This is the smoothest gameplay I've been able to make with [Hildryn], with ~8000 shield tau forged without shards, full armour striping and being super tanky!
Arcane Intention allows us to [Reach] 1050 base HP with 3 channeling abilities: Gloom, Haven and Balefire. Replace with Arcane Aegis if you don't have one r5.
