[Kaleban]

I believe "named" items, such as the Ring of Gaxx, Ring of Earth Control, can be combined with magical armors, cloaks, and necklaces. Items like Rings and Amulets of Protection cannot be combined with armor unless its "special" (such as Dragon Scale Armors), and can never be combined with each other.

Experiment, but I find that for ANY spellcaster, use the Robe of Vecna and Amulet of Power. If you're distributing equipment around, the Ring of Gaxx really belongs on a Tank-type, as do any protection rings you've got. Unless you have Aerie meleeing (why oh why would you put a 50 lbs winged elf out front to take hits, especially when her bones are hollow????), always wear spells-enhancing equipment. the Cloak of Mirroring, Displacement, et.c DEFINITELY belongs on your tank-type who draws fire from the bad guys.
