If your problem is dying you need to be more careful on each boss. Dodge Lilynouch/Leviathan ground attacks with jump attacks or just jump if you're not confident. For Dodo you can dodge his attack/manipulate it to go over your head if you're really meticulous but it's more taxing on time.

Of course damage helps, that should be obvious (more % boss, % dex, % total damage, etcetc). Another thing that might help is a max HP pot if you're still having trouble surviving.

I wasn't aware their attacks were dodgable. I suppose I'll try it again but in CYMK I need under 20 minutes to place.

I feel like I've spent enough money on this game over the years, sooo....
