I know this looks weird, since it is built for Shieldgate without any energy to shield mods. Or energy [Regen] mods.
But with [Catalyzing Shields] it has 74 base shields, 2 augur mods on the [Grimoire] give us 80% energy to shields. Nourish costs 111, and gives us 88 shields per cast of Nourish.
Energy is fixed by either [Xata Invocation], Arcane Energize or a Violet Archon Shard for 20(30) health to energy. Nourish will turn each 100 health orb into 63(95) energy with a single Violet Archon Shard.
[Precision Intensify] and full Molt Augmented stacks makes Bastille full strip enemies in 2.83 seconds.
This build will easily go to level cap. It can augment either your weapons OR just go off ability DPS since Nourish buffs [Flechette] orbs.
For more damage we can replace Arcane Aegis with Arcane Avenger. This benefits both our [Flechette] orbs and weapons.
