This is the upgraded version (featuring a umbra forma) of my Variant 2 Saryn build (cheaper build without umbra forma linked at bottom)

Gameplay mostly consists of spamming spores, only use other abilities if energy is plentiful or at max
([Corrosive Projection] can be dropped for energy siphon if you are not getting any pickups depending on how you are using this build)

Personal Customization Notes:

• Arcane Grace can be dropped for any other arcane based on your weapon loadout or preference
• If duration is not needed primed continuity can be dropped for regenerative molt (recommended) or any other mod you prefer
• Augur reach can be dropped for Augur Message/Secrets (Duration/Strength/ respectively) based on what you prefer over extra range

Work In Progress:

• Experimenting with helminths
