I'm not sure how casters could not possibly realize the benefit of having HF.... ? I play on every server, though my sorc is on Ghandalla, she has the HF necklace item you get from the mines (turned in 12 coals(?) to get the HF necklace). Had it on her since she was first able to wear it and will never replace that neck item unless I find a robe of SR and HF (miracles can happen).
Didn't realize CON was the dump stat since I put everything I can possible into CHA? I think my CON is a 12 at best. So my sorc has approx 2700+ sp (forgot exact amount) at level 15 (32 CHA). Besides aren't casters supposed to try to keep in the middle to back area away from melee combat and getting hit by anything? If a caster is in melee I usually mentally bet their death in a few seconds. Robes vs Full Plate/Half Plate or anything armor, my bet is robe = fail.
So any advice/opinion on what I've done so far is appreciative.
