Corum
I would go with the sword that has 80 Damage, which u mentioned. WIth the Sword of Gods, u can't go over 71-100 Damage, that I have seen. My sword which is a god sword, does 71-100 plus has Frost(5), Mana Drain (3) and other goodies, but only has 1 Charm (Oh well).
So I would go with the sword that u have and enjoy beating every enemy in the rest of the game, basically except of course the bosses, need a few more hits to finish them off (DOH!).
