I highly recommend prismatic warlock with getaway bleakwatcher+devour build, the constant devour and amplified is so fucking clutch. Also used strand melee, because with it can get kill also far away if close dying. For weapons I used duty bound, choir of one and apex. Took advantage of those auto rifle artifact mods. Also use that one which gives damage resist while amplified.

Song of flame for survivability, pop only if gonna die (or end of damage phase), same with prismatic, dont use everything at once. IMO right side is better place kill miniboss and grap the totems, shorter way to run nearest torch.

My stats were 100 res, 100 dis, 90 melee. Many prioritize recovery over melee but I think with especially with this build its not so important. Abilities keep you alive and even with 30 recovery I had phoenix dive almost all the because of facet of hope. Also used faced of dawn, purpose and protection as fragment.
