I'm pretty bad at the game so I didn't go 100% damage, I included a few survivability items like the cassim's cloak, vamp glasses, and messy prescription. Still, I think this build is pretty close to the maximum potential dps you could acquire in the game. One way to improve it would be to do more loops to keep boosting the cartographer's quill. I've gotten it up to around 240% before. I don't think there's a limit, but the bosses get insanely fast after about 8 loops so it becomes difficult to stay alive that far unless you're using a max armor or evade build.
