Monsters fleeing

This bug is very limited, and can only be reproduced using level editors. It's possible to change the conduct of a monster so it flees from the player instead of going for him.

Steps to do it
Put on the same spot three copies of the monster, facing north. Each one only appears on one different difficult level. It's recommended choosing a Demon as the monster, as it can't attack from distance.

Put the player aligned with him, facing him from the south. If the player is too much on the left/right of the monster, the effect dissapears.

Final Effect
The final effect is a monster that flees from player until it's stopped or he moves too much to the left/right. You may need to shoot to activate it.
