Basically here are some tips I used to get through it this month. Bring a delay unless you can hit for 8 billion damage without an active. Stall for the delay on Chester. I brought a Mel just for this. Chester will spam you with posion and hit you for 29900. All you need to do is heal to full when he hits you for the 29900(every 3 turns). Amon is a Physical, Devil, healer... bring killers. I would recommend servant, Caster if you have one. Anyone else have any tips for the dungeon. Or anyone want to share a crazy strategy they used?
