Do we know the portal is one way, or only the amulet? Even if the portal 
is one-way, there seems to be an enchantment that allows viewing the 
destination, so the amulet could be some sort of magical laser pointer 
that would be necessary to cover the fact that the minions can't see 
their master after the go through the portal. It doesn't explain why the 
  delvers can see him, though.

Also, since the portal seems to be elsewhere on the same plane, 
maintained spells will still reach even if the distance penalty for 
casting them is -3520. This is a tremendous disadvantage for the 
defenders, who might disastrously crit fail attempting to cast most 
spells on the lich, and at best be ineffective. They'd have to use 
spells that take long distance or other modifiers instead of -1 per hex.
