Bark! Bark!!
Fortunately for you it's only 40 floors. And I'm pretty sure a few of the enemies don't actually respawn. But yeah, you definitely have your work cut out for you. Last floor is like 3 Darknuts simultaneously.
Ugh I think I can make it to about floor 25. I like to fill my bottles with that soup from the Ice dungeon and I tend to use all of my arrows by around the 15th floor. That last floor sounds like hell. Ps does it help if I finish the temple in the sky I think I have the Item from that temple but I cant remember.
