Make it less likely the demon axe will trap the player.

* Mesmerisation no longer works through translucent walls.
* The demon axe will only cause the player to be mesmerised by one monster
  at a time, so the player can't be unable to move due to monsters on two
  sides.
* Preventing noise from stopping the demon axe's effect actually works.

This still leaves monsters that can't or won't reach the player in the
middle of a deep water or lava pool as a general mesmerisation issue (that
sewer vault with the siren at the end, for instance).
