Byron's Ghost - They only carry them around, they haven't attempted to use them from their sack/bag and I think they always intended to retrieve the plates first... and for the haversack that is a free action IIRC.
painangreed - I have informed them of this as well (most recently in the case of the spell Spell Vulnerability from the Planar Handbook which someone else has a thread on).
Mista - Divine Intervention? Interesting you should bring that up... This group is currently mulling the idea of convincing an NPC to lobby its master, one of the two aspects of Demogorgon, to, get this, PAY THEM!... for foiling the other aspects plot. Pay them.? I mean seriously...? My idea of Demogorgon paying them is by, at best, letting them lead some raggedy band of Dretches into the Blood War!! Which sounds especially good to me right now.
