SLASH'EM introduces a number of monsters similar to the Floating eye. Unlike the floating eye, the new monsters possess offensive gaze attacks and will use them on you whenever they get a chance. All are also mindless, making it more difficult to approach them after blinding yourself to avoid their gaze.

Glowing eye Edit
Bloodshot eye Edit
The gaze attack of the Blinking eye is identical to the attack of the Quantum mechanic. It has the same speed as a player without speed and will cause you to teleport on every turn that it is able to lock gazes, making it extremely annoying to approach without either a blindfold or teleport control. Eating the corpse of a blinking eye has a very large chance of conveying teleportitis.
