I have a player that has attuned to an Orb of Dragonkind and failed the check to avoid being charmed by it. This part of the item applies (emphasis mine):
While attuned to an orb, you can use an action to peer into the orb's depths and speak its command word. You must then make a DC 15 Charisma check. On a successful check, you control the orb for as long as you remain attuned to it. On a failed check, you become charmed by the orb for as long as you remain attuned to it.
While you are charmed by the orb, you can't voluntarily end your attunement to it, and the orb casts suggestion on you at will (save DC 18), urging you to work toward the evil ends it desires.
The other players are aware that this character has been charmed by the orb, and are trying to figure out a way to break the "curse". Can they do it? If so, how?
A couple of things that come to mind:
- Remove Curse. I'm thinking it doesn't work, as this is not a curse, and the item isn't, strictly speaking, cursed.
- Greater Restoration. This should work in theory: "You can [...] end [...] One effect that charmed or petrified the target". But it won't remove the attunement, and the text of the object says this applies "as long as you remain attuned to it"
- Disintegrating or otherwise destroying the orb. Would definitely work (it's listed in the object itself), but the characters don't have that ability yet.
- Breaking the attunement, for example by hiding the orb out of range (see Can you break somebody else's attunement on a magic item?). This should also work, and is probably the easiest way, but I'm trying to think of all possibilities.
