Hello from russian roleplayers!

I have a question. I have a small creature in the campaign, which is a reasonable container for a huge amount of magic (completely immortal NPC and even Wish cannot do anything about it). Can a warlock with a patron of a Genie move into a genie's vessel with this creature, if it does not agree? Or are there any restrictions on the objects moved into the vessel?

You can only bring creatures into the Vessel with the Sanctuary Vessel feature - and they must be willing to go in with you. If they don't want to go in - you can't force them to.

Thanks! But they also suggested to me the idea of being imprisoned in a precious stone 9lvl

So are you asking how to capture a creature that can't be killed?

That depends on how strong it is.

• Normal creature, but is immortal: have you considered chains or a cage?
• Creature with powerful magic including teleportation etc: Imprisonment might work.
• Not a creature, a godlike being: only what the DM says works, or maybe stronger gods.
