Yeah, it's a solo Nerscylla with Tree Swing to jump over monsters and walls and a tutored Drift Slide to go over water, around/through corners, and down hallways to escape enemies. Sleep Sac is good when it works, and the fourth slot is Bubble Bath to clear poison / exist because I don't have anything better. I think I can guess what Hypnotic does, though I don't have a Hypnocatrice to channel it from.
Anyways, I've only tried maybe 4? attempts of it, and it always fails in the 30s or 40s after something like jump over an enemy -> they still hit with a 2-tile move or projectile -> run away with drift slide -> right into a second enemy that makes the spider explode. It's fun though, you can blaze through the floors real fast when you don't fight things.
But yeah, my high score was with four monsters that actually fought enemies, so don't worry, playing the game the intended way is still more effective. :P
