[Baruuk] in all of his glory.
I'll preface by saying I have not used this past 3 hours in SP. However even at 3 hours it was really too easy. Never came close to dying, I never even lost a shield. The DR this kit brings coupled with Adaptations DR makes you insanely tanky. His modded Strength + Molt Augmented makes for a good time for you, and a not so good time for enemies. You literally obliterate everything.
Main points here his 1 has been replaced with Pull due to needing everything to get up close and in your face so you can keep the combo counter going. Fat red crits are all you're going to see. Keep his 3 active. His 3 only counts to +9, I know you can have +20 and so on and so forth but that doesn't matter only the first 9 shards matter. Recast when its getting low to keep that restraint eroded. Pop his 4 and kill everything. I personally don't use his 2 much however his 2 is also useful for keeping the restraint down.
Other than that I run an [Epitaph] with cold to slow down Acolytes and the like. Armor strip isn't needed. My Stat stick is pretty simple I use the Kronen Prime modded for Combo duration Crit damage/chance and melee damage. Pretty straight forward.
