Personally, I would just treat the "magic tattoo" as flavor text on a background, and just make a "Were-Dragon."

Why not.  Billy and Georgia need a laugh.  Who knows what Terra West would do.....

Sorry ... my inner geek can't resist: "Wouldn't a solid gold fiddle weigh hundreds of pounds and sound crummy?"

Ironically enough, that episode was on Comedy Central last night.

Well, except for Holy, the powers are ranged. One is +1 to hit when using it from True Aim. That's a Stunt attached to the gun. All Creatures are Equal has no range added to it. In fact, it doesn't even say it has to be the Weapon that does the damage (although it could be implied to be that way). One guy I discussed the Swords with was worried the Knight would use it and then toss and hand grenade at the baddie.

I think we're just going to have to agree to disagree on that. The strong implication in the Sword's description is that the sword itself must be used as the weapon in order to take advantage of the All Creatures are Equal

Personally, I, as the GM, would rule that you would need to use the weapon in question, to take advantage of All Creatures are Equal.  On the other hand, just having finished rereading Small Favor yesterday, I can see how people could use it to justify not needing to use the actual holy weapon.  

They would probably argue, 1) that is why Sanya uses his assault rifle, and even more 2)
I know, I didn't need a spoiler tag for that, but hey, you never know who may be reading these things.  

So, I guess it all boils down to how permisive is the GM.
