If you're talking about the place with the slimes that instantly KO you, then you want to make sure you are sprinting with Shift. The last slime can be either rushed past, or baited into a charge and you can slip back where you came from and it'll miss.

If you're talking about the caverns with the slime dragons... it can be quite difficult. I'd definitely recommend using your Documents Case in your Key Items to stock up on healing supplies from the Wizard back at the main camp... and making liberal use of Fire Bolt if you managed to acquire that.
