[Gil-Galad]

I'm stuck with the beholder & friends, and I am in dire need of some inspiration here...

1) I can't beef my party up with spells, as he casts Dispel Magic every round.
2) I can't cast any spells during the fight, as they all fail for some reason.
3) I can't seem to protect my weaker party members, as they stand closer to the monsters.

In other words my Druid, my Sorcerer, my Wizard/Cleric and my Rogue have all died in every attempt - actually my only result so far has been my Paladin standing at the end.

As I see it, you can only fight your way out of this - are there any good tactics out there??

Here's the chosen 6:

1) Aasimar Paladin/4lvl Fighter
2) Human Ranger/4lvl Fighter
3) Halfling Rogue
4) Dark Elf Sorcerer
5) Human Wizard/Cleric (even lvls)
6) Tiefling Druid

All are about lvl 15, and they all have missile weapons, however #4-6 are, quite frankly, dummies when it comes to meelee.

P.S: I know I can turn the difficulty down or ressurrect fallen comrades, but I'd rather not...
