Divinity just seems blatantly overpowered at the time being. Just get the head that heals, the crown that deals insane Divinity based damage and the arm that stacks Divinity on decay + the arm that decays on start and your only challenge is the mirror match. Everything else just has no chance at all.
I just faced myself in stage 8.
Happened again in stage 5.
Then again in stage 6 of the same run.
And again stage 8 of that run.
It worked just fine for the first however many days of the patch. But I'm guessing either my dynamic IP has rolled over (if that's how you stop it) or something broke at some point. Because now it just isn't stopping it at all.
