Asylum shade lich..., Skeleton Lord's are tearing my tanks a new one! Options

[olimikrig]

Tried everything I can think of here.. The lich itself isn't really that much of a problem, the skeleton lords, however, are simply just too much for my front-liners. They are tearing my tanks to pieces within seconds. I don't really understand just wth is going on, I've dealt with other skeleton Lords before, and they weren't too much of a problem (the planar sphere demon fight amongst others).

My party is (all lvl 13-14):

Vagrant
Berserker
Anomen
Valygar
Nalia
Imoen

Heck, I've even tried resorting to some cheesier tactics, bottlenecking the Skeleton Lords in the corridors back towards the crystal area, but I still only seem to be able to get one of them down - at most - before my melee guys start dropping like flies.

Any help would be greatly appreciated as I'd hate to have to end up resorting to lowering the difficulty.

SPOILER!

(Hmm...all Skeleton Lords are the same, imo...) ;]

[And that's why, amongst other reasons, ranger/cleric will always be better then Anomen - ironskin. He can absorb quite a punch, at least one SL should be dead until ironskin refreshment. R/C rules!]

Critto's advices are very good, nothing more to say exept one thing, when using summons make sure they're not blocking your fighters way to the skellies.
