First thing people may notice is the low efficiency on this build, but the thing is you don't need a good amount of efficiency with [Nidus] due to the energy steal from his 1.Use [Growing Power] for extra power strength added with his 3. [Nidus] needs barely any efficiency since only his 1 and 2 use energy.This build will mainly help you survive by using enemies as meat shields.You won't need energy since of [Hunter Adrenaline] which is going to help you out by a long shot.
