Aha, just rememberd what I was thinking of. The Ankheg armour cannot be used with a Ring/Cloak/Amulet. I never bothered trying with any of the others.

I felt really stupid after having Ankheg armor made for 5000 gold and finding out I can only sell it same price as full plate Really what's the point of it?

Not much, especially considering full plate is plentiful and ankhegs are rare in BG2.

If I were you, I'd just create my own stuff!!! yesh, the artwork would still be bad though...

Anhkeg plate: good for Viconia or Aerie.

Yeah Anhkeg is very light weight. Armour of the Hart is good. (AC -2 I think.)
For a fighter try the amulet that reduces saving throws +2 or the one that increases magic resistance +15%.

Suul Yinn, I think the paper dolls in BG2 were REALLY disappointing. Even a femme mage looks unsexy. Worst part of a great game.
