  That is probably because move_block is not set on the walls.  The attack 
doesn't see anything that stops it, so it keeps going (I'm presuming we're 
talking arrows and spells here).

  As Alex states, monsters use a bit different sight logic.  More on that in his 
message.

  move block and blocksview are not tied to anything. You can have a wall that 
blocks you from seeing through it, but does not block movement.   Likewise, you 
can have a wall that you can see through, but can't move through (the walls 
separating the entry area from the shop area of the scorn shops is an example of 
that).

  I think the real fix here is to make it so that the earthwalls block movement. 
  that sort of fixes the problem - the monsters still know where you are, but 
can't get to you through the earthwall.
