Gloom in this build reaches its max potential %95 slow gap with Growing Power and will make enemies stop which gives our warframe so much survivability and also with Umbral Vitality we increase our survivability much more. The bad way of this build is.... efficiency.

To meet the low efficiency we use Arcane Energize, Dethcube Prime with Energy Generator and of course Zenurik which is enough for your energy pool to stay full filled.

Since Saryn Primes 3rd ability Toxic Lash buffs melee so good we go for Arcane Strike to buff our melee more and proc melee status more often. Using Arcane Strike leaves us 1 more mod slot for our melee weapon by not using Primed Fury in our melee setup.

Here you can check the melee setup I prefer for [Saryn Prime] : Orthos Prime for Saryn
