AANND im done with Jugulus Eximus 5\5. After hours i understand something:
Need to kill mobs around Purifier but dont touch it. Bcs it spawn mobs with other lvl scale (etc), origin environment have % to spawn eximus.
And not matter 2nd, 4th or 5th mission, just started Salvage with 1st step Purifier (possible not necessary ??)
(possible not necessary of 1st step for Purifier??; there is 2nd type mission where purifier can spawn at 1st, cant remember which one, mb with greneer pic)
PS; i preferred to play solo, Fass. Spawns at first 5~10 minutes, or restart.
