The Mace of Gygax

As new seasons of Futurama are coming out, I've been rewatching it (and enjoying it greatly - the first 3 seasons in particular are excellent).  

In season 2, episode 6, Gygax hands Fry a +1 mace.

How should we stat such a weapon?

Sure, it could just be an ordinary +1 mace... but it's the *Mace of Gygax*!  That isn't enough!  But if it's *not* a +1 mace... 

The solution is simple.  The Mace of Gygax gives a +1 bonus to attack rolls and damage... aaaaand everything else.  +1 to skill checks and saving throws.  +1 to initiative and AC.  +1 to hp.  +1 to strenght, dex... +1 to level.  Basically, anything that has a game statistic, +1. 

I like to think that Gygax would approve of this.  Best part, this works in almost every rule system :D
