This is probably my best build yet. I just defeated double bats with this build AND the fox guy. Well see how far this goes.
Made it at floor 17. I got to the shadows and couldn't keep up with them and lost. I needed more regen. Also, I found out that the damage increases the more you deny the curse...I got not 1, not 2, but 3 double shadow encounters at the end...unfortunate to say the least, but the farthest I've ever gotten thus far.
