People have been recommending to use unlimited fairies, unlimited mana, no cooldown skills, money not decrease and fight bosses only. I have been playing using this mod for about 3 weeks now and learning from experience that if you ever get too far from where you're supposed to be, you will get banned. like this one time I tapped a lot of times on updating new heroes, although I was still week and had a few artifacts, and I jumped 2k stages and got banned. I have not been banned for prestiging several times (upgrading artifacts). what I'm currently doing is jumping a few stages with all spells activated while using clan ship with that one skills that summons a clan mate, and spamming the clan mate (infinity faerie allows that) gets me really far. then I stop and upgrade shadow book + all main artifacts for that build and do it again.
tbh it can get a bit boring, since I have to wait 2 min between prestiges, but so far I'm 10k. I'm looking for a better/faster build though. maybe with the -1 MS jump we will be able to speed up that.
