In DnD 5e, there is an item called the Deck of Many Things.
There are many possible cards that can be drawn from the deck. For example, one might draw the "Donjon" card, which has the following effect:
Donjon. You disappear and become entombed in a state of suspended animation in an extradimensional sphere. Everything you were wearing and carrying stays behind in the space you occupied when you disappeared. You remain imprisoned until you are found and removed from the sphere. You can't be located by any divination magic, but a wish spell can reveal the location of your prison. You draw no more cards.
As a player, I don't see how it would be fair for something like that to happen. Could the effects be nerfed or something so it's on the same plane of existence?
I just want to know what a GM would do if a player pulls the Donjon card; should they stick to the rules or nerf it a bit?
