We really could use a Healer-Type character. Zander while reasonable with the Heal Skill can really only repair his golems hitpoints, he is not able to heal himself. Still being an arcane caster he can cover the Arcane Magical Side of things we may encounter.
Wands of healing are good and Zander can certainly try and UMD one. However Wands/Potions are poor substitites and don't provide ways to cure crippling conditions like Disease, Poison, Paralysis, Ability Drain, Level Drain or other nasty things.
None of the usable classes have access to divine magic our best bet is to have someone train umd, howver I trust we wont see that much of that hopefully
