Derfel Cadarn, Liches are immune to lvl 5 spells and below, and so Breach is useless. You need Peirce Magic (lvl 6 but not as effective as the two lvl 7 ones), Ruby Ray of Reversal, or Warding Whip. If neither Aerie nor Edwin can cast 7th lvl spells, it'd be hell fighting Liches [img]smile.gif[/img]
ADD: What you encountered were Liches' casting spell protection (your magic won't work) and combat protection (physical attack won't work) spells onto themselves. The spells I mention are the protection dispelling spells that would work on Liches.
at any event, you can always run away or use summons, and wait until Liches' spell protections and even spells to run off, and then come back to kick their butt (assuming you're not playing the tactic liches).
As for Beholders, L* do a search and you'll find many beholder hating threads

There are cheesy beholder killing items to get in the game; you can also use traps -- skull traps the beholder killing spell [img]tongue.gif[/img]
