• Flexible build ([Adaptation] as a flexible mod slot) is 3 forma instead of 4 if you use a rank 8 [Equilibrium] instead of max rank (remove additional dash (naramon) polarity).
• Build is 3 forma instead of 4 if you don't intend on swapping [Adaptation] for any other mod (remove additional dash (naramon) polarity).

Swap adaptation to become less tanky but have slightly better quality of life.
These improvements can be with regard to:

• Range (augur reach)
• Efficiency --> health drain from Despoil, casting Shield of Shadows and the occasional Terrify (streamline)
• Shadow duration (primed continuity/duration mods)
• Strength (intensify) I personally would not do this but you do you.

--> Bring a nice slash weapon into your mission
--> Activate Desecrate
--> Kill some strong enemies and create their shadows
--> Farm

SLOT B: Max range Desecrate
