Arcane Impetus in place of Molt Augmented. Arcane Impetus will ramp up much faster due to how Mesmer Skin and Reave spread status effects, I have yet to test if your thralls will also trigger Arcane Impetus.
If using Molt Agumented then instead run 0 Forma, [Augur Secrets] in place of [Intensify] and [Boreal's Hatred] in place of [Overextended].
This build uses a bunch of range to spread Enthrall from the energy pillars you generate by spamming reave around the map. Nourish is here to keep our energy topped up. This is less of a bossing build and more of a survival style build.
