This was definitely my best run yet. Got to magma cave in endless. endless. I was able to generate up to 200 poison and weak on an enemy and got out of all fights with max health but these dudes are just too strong. There's no way to generate enough block to block the burn damage, weak doesn't affect it and there are 3 of them generating 20 to 40 burn each turn.
I suggest adjusting the difficulty for endless if that isn't planned already cuz even the fights before took forever even though I basically couldn't lose. It got kinda jarring. Other than that it was really fun!
