K I'm just gonna share this since you won't find this strat on youtube (to the best of my knowledge) and it was what I did to get solo flawless done a week ago. Encounter starts at 1:05. Some modifications to weapon choices were done in future attempts but the strat stayed the same. Instead of Thorn and Abyssal Edge, use The Call w/ Slice and Dragoncult Sickle (or some other caster frame sword). When you drop your cade hit the 2 shriekers with The Call to sever and with the artifact perk To Shreds boosted. When dps is over, stay and kill wizards and the orge guarding the wheels nearest to spawn, all from the dps spot. When a certain amount of resonance is on the ground, wizards stop spawning (20-25?). Easy chill 30 minute 4-5 phase. No 8h+ run bs.
