I am a High Elf Cleric 28th lv and I have decided to take the route of being
the healer of the group and nothing more, fighting only in small batles, but
in the larger more drawn out fight I find myself hanging in the backlines
like a pure caster and just keeping everyone alive with heals, even medding
in the middle of the fight just so i can get up enough mana for that one
last heal. I've benn colecting alot of +wisdom item and sacrificing AC for
more WIS. My natural wisdom is only 105 but it is now at 162. my equipment
is:
BloodStaind Tunic (+4wis)
Adamantine Epulotes (+7wis)
Black Iron Medalion (+3wis)
Rune Circlet (+4wis)
Silver Ruby Vail (+3wis)
2 Polished Bone Bracers (+3wis each)
2 earings (+3wis each)
2 rings (+6wis each)
Plat Armband (+3wis)
Chared Gaurdian Sheild (+9wis)

I have lost at least 20ac if not more by using these items but if your
working in battle with a good tank you shoudn't have to worry much about
getting beat on alot.
