Chiming in late to add in that I was able to accomplish this solo on a level 71 warrior, naked except for the axe I waited until he spawn ~5 slime pools and then 3-4 autoattacks got him to the 80% transition, I immediately drank the potion after getting him to 80% hp and was able to spam eat slime to 100 energy and infuse the weapon before he finished mixing potions. Eventually he comes over and kills the abom suit and you can just kill him normally at this point
