I'm sure it would be a pretty deadly sword against other creatures as well; I doubt the gods simply grabbed a rusty claymore from a farmer's shed and used that. It'd doubtless be physically powerful, made of Mithril at the very least, and more likely something morals don't even have a name for. Probably has plenty of power to spare, having gotten power from all 21 gods. Short version, I'd not mind having it about to hack up goblins. And even if it's an ordinary piece of metal against mortal creatures, it'd look pretty nice on the mantelpiece.
