Fits in [Umbral Vitality] instead of normal [Vitality] and swaps out [Power Drift] for [Primed Sure Footed] and [Augur Message] for [Augur Secrets]. This results in a slightly higher base gloom slow (82% instead of 75%) but keeps you on your feet allowing for more DPS and far better survivability IMO, you will have to re-cast silence more often but that just lets you abuse shield gating better. Aura forma allows for running [Brief Respite] to allow for shield gating abuse combo with [Augur Secrets]. If not fighting infested or modes with massive amounts of toxin you can swap [Umbral Vitality] for another mod of preference but its bonus to [Umbral Intensify] is extremely helpful.

For Arcanes, I find Energize all but required to keep this build powered and Arcane Strike can be swapped out for any arcane of preferance. Given that I run this with my Prisma Dual Cleavers or some other well built melee that can use attack speed I prefer to use Strike.

[Augur Secrets], [Umbral Vitality], and [Primed Sure Footed] are option mods, you can swap those out and replace them depending on playstyle.
One option is: swap [Umbral Vitality] for [Rolling Guard] and [Primed Sure Footed] for [Power Drift]. This swap would give you an invulnerability window which when combined with the Carnis mods on your weapons and using a heavy attack melee allows you to get the bonuses of [Primed Sure Footed] with minimal impact to your power str.
