Growing Power can be swapped with Brief Respite if you want a comfier Tanking/Shield Gating Experience.

Bellicose adds 72% Ability Strength when 4 is activated after activating Crepuscular.

Update 1-13-26:
Wanted to provide an update and respond to the comments on the build:

• Yes, Silken Stride Snapshots and that's why I use Crepuscular or Growing power to reach the Arcane Bellicose HP threshold for 72% Str.

• "Why not use Molt Augmented?"
  On paper Molt Augmented always "looks" good, but in practice doesn't compare. Looking at both arcanes, at max strength, on this build puts you at 289% Strength (Crepuscular) vs 319% Strength (Molt Augmented). 30% extra ability strength is outweighed by 3x CD bonus 10/10 times, since you're essentially taking the damage buff from Silken Stride and adding a multiplier onto it, rather that going from 156% Weapon Damage to 168%. At a 100 base damage you're only going from 256 Damage to 268 Damage, which is only a 4.7% damage buff going from Crepuscular to Augmented.

• "Violet shards aren't as powerful as [Equilibrium]"
  True, I'm not saying they are. But at a base 200% HP and 50% Energy Orb drop rate giving us 862% and 215% at max strength. A single execute from Mercy's Kiss will net us a minimum of 8 HP orbs and 2 Energy orbs for 150 energy with a single tauforged Violet archon shard, and freeing up mod space that would've otherwise been taken up by [Equilibrium]. That's also only assuming orbs generated from [Oraxia] herself, and not any other forms of orb generation via companions, squad members, and containers. With mercy's kiss being a very consistent ability for shield gating due to how easy it is to quick use while in silken stride, and being incredibly strong to the point of being able to full execute necramechs, there's no reason to need Equilibrium as a mod.

• [Catalyzing Shields]
  With invisibility and on demand shield generation from [Augur Reach], you could optionally swap out catalyzing shield for any mod of your choice. If you're looking for more strength [Energy Conversion] is valid since it is consistent in tandem with the use of Mercy's Kiss. Alternatively a [Vitality] mod is also viable as it gives more value to Arcane Bellicose at the start of the mission, giving Silken Stride more strength from the start of the mission.

Helminth Options:

As much as I love the numbers on Webbed Embrace, I'm not a fan of it's practical use especially on a build with as little strength as I have. Alternative abilities suggested would be:

Lycanth's Hunt: More energy and health orb generation on a infinitely refresh-able duration.
Nourish: Added Viral damage, and increased energy generation.
Pillage: More consistent armor/shield strip and shield gating. (Pillage scales well with high duration if your range is low)
Bright Bonnet or Empower: For the people who are seeking more strength in the build.

Why Crepuscular over Arcane Camisado?
You'll get the same full benefits from Bellicose with just Crepuscular and a 30% additional
strength from Camisado has signifanct diminishing returns compared to +3x Final Crit damage

Archon Shards:

1 Violet [Equilibrium] Shard (it's free)
1 Emerald Corrosive Stacks Increase
3 Emerald Toxic Status damage increase
