*This version of the build costs 1 additional Forma and drops duration and efficiency from the base build. To see the base version, look here.

Swaps:

Energy Siphon:

• -> Corrosive Projection (armour strip to the max for higher levels).
• -> Growing Power (If her 3 can trigger this, would help her 1 recast to be stronger).

Umbral Vitality

• -> Adaptation (Additional Survivability, 8% res for 16s up to 90%).
• -> [Primed Flow] (if other energy methods don't give enough).

If you don't Forma the Augur Reach, as in the 3 Forma Version, then these are your options for the Umbral Vitality slot.

• -> Regenerative Molt (Healing on your Molt).
• -> Adaptation (Additional Survivability, 9% res for 18s up to 90%).
• -> Contagion Cloud (if you like gassing with toxin).
• -> Hunter Adrenaline / Rage (if energy gain isn't great, good in combo with Survivability options below).
• -> Flow (if other energy methods don't give enough).
• -> [Augur Secrets] (More Strength and shield buff).
