If a creature with the ability to swallow other creatures is banished what happens to a still living swallowed creature (i.e. PC)?
The banishment spell has the following key points:
- "You attempt to send one creature that you can see"
- "While there, the target is Incapacitated"
- "The target remains there until the spell ends"
The thing is, you only targeted one creature. So what creature(s) are affected in this situation and how? You can't see the swallowed creature, so how is it affected? I can see several possible scenarios:
The swallowed creature is left behind. Could be a useful way to save someone swallowed.
The swallowed creature is also banished. It is treated the same as the banished creature and is also incapacitated. It may or may not take ongoing damage during this time (for instance the acid damage from the stomach).
The swallowed creature is also banished. It isn't affected by the incapacitation and could fight its way out of the creature that did the swallowing. If it gets out, it is just in the demiplane alongside the banished creature. It may or may not stay behind in the demiplane since it wasn't the target and the spell fails to pull it back.
Background: Our party is about to face a Kraken (party member stole from the temple of the God of Sea and Treachery despite the cleric vehemently warning against taking anything). This thing seriously outclasses us (level 10 party members) if it is the full version of the Kraken.
We've faced a baby version of this before. If this is the full CR23 version, the only thing I can see that can get us out is the cleric's Divine Intervention, running away while it is banished, or an exploit like being able to banish the creature with someone(s) inside who can then escape and attack it without being attacked in response.
