Heaven and hell are
interesting places.
That spell sounds cool. After however many questing hours it'd be such a suprise find. It would have to be hella powerful, as it is connected wih God. I doubt they'd actually put that in their game, because like someone said the Div world already has its own religous lore. Then again, who cares about how religiously correct a spell or weapon is.
How about the idea of certain weapons having unique abilities.
That would be better than all weapons merely having different stats.
Some RPGs have that, I can think of a few japanese ones that do, a sword or ring..hell, most of them do.
But for a D&D style RPG, unheard of..
From the simple to the huge..a dagger that can chop bark off a tree and imbue it with healing properties..
or a rusty old staff that suprisingly summons satan..
