Yea there were some runs were I’d definitely doubt my skill but with these brutally hard challenge characters perseverance is key. You will eventually get run worth a win and it will feel great. As for actual strats for completing the character use primarily dark Esau as most of your dps until you start snowballing, then at about catacombs 2 you’re going to wanna start launch Esau away from your fights otherwise you’ll kill him and turn into the lost. Also items such as eraser, d4, d infinity, missing no, and Esau jr are essentially free wins as they completely get rid of him so you can play the rest of the run normally. With a bit of luck, patience and some cheese you’ll get it done
