I was wondering if the Infinity Gauntlet is considered an object. If it is indeed an object, would the DKR Catwoman with the Cat Burglar ability be able to affect it? Thanks

No, it's not an object.

It is a resource.

The Gauntlet is not an object, it's a resource. It's arguable that the gems on the Gauntlet are still objects, but the other issue here is that Catwoman can use Cat Burglar on objects on the map or being held. The Gauntlet isn't held, it's assigned. Relics will fall into the same case: she can effect them while they are on the map but not once a character has successfully rolled for them.

Thanks for the info!
