The best way to "godify" yourself, as you say, is to train all your magic skills as high as possible. Then, enchant an item to raise each magic skill over 105 (over 110 is preferable). While wearing those items, you'll be able to cast ANY spell in those magic schools for the minimum spell point cost, no matter how powerful the spell is. For example, Spell Reflection Duration 60 + 60 per level, Chance 100-100 + 100-100 per level, and it only costs 5 spell points to cast! This essentially makes you immune to all magic except paralysis, disease, and poison.
My favorite effect when I'm hanging around in town is the Raise Reputation with All.
