banishment + magic circle + planar binding

[khachaturian]

is this workable?

- so you're fighting a demon and cast banishment; he gets sent back to baator
- your allied cleric/paladin/wizard/warlock delayed action until your turn and then casts magic circle
- on the demon's initiative, he is hanging out at home saying hello to the wife and kids

one minute passes and the demon comes back to the same spot on the prime material plan where a magic circle has happened to pop up.

you cast planar binding

profit?

Was the Demon you were fighting dumb enough to give you his true name before you banished him?

If not, how did you target that specific demon to bring him back?

Also, does this not just troll the demon? Sure they are jerks, but you are already tearing the guy away from his home dimension and forcing some slave labor/gladiatorial combat on him.

You don't need the demon's true name, and you don't have to target it again. As long as you end the banishment spell before its duration expires, the banished outsider reappeares at the exact same location it was banished from.

Unfortunately, magic circle has a casting time of one minute, so you can't cast it before the banishment spell would expire. What the OP said still wouldn't be possible, but for an entirely different reason.

Respectfully,

Only spells with a time of 1 action can use the Ready action.
Magic Circle casting time is 1 minute.
Banishment max duration is also 1 minute.

I couldn't find anything (albeit a quick search) in the casting rules about when you select the AoE for a spell, meaning a DM would be free to rule say you do so when you start casting. Thus try starting Magic Circle a round before and you have to be sure the demon is still in the AoE when you cast Banishment. Cast after Banishment well logically it happens after so a lot of the same issue.

Nevermind well... where does it ever say time is absolutely precise down the second with these things? Your performing a ritual of the ancient world before mechanical clocks were widespread (and those that existed aren't necessarily exact or portable) they don't make sense to be exact things you can precisely time easily. Indeed even the round "represents about 6 seconds in the game world" so time is explicitly imprecise.

On top of gimping two of your casters for an entire battle (maintain Con, don't want damage) presuming the demon isn't alone and the saving throws open to the demon this seems a fairly low-percentile strategy on the whole.

What if the banisher is a sorcerer using extend metamagic?

[khachaturian]

but the whole idea of turning a bbeg into your pawn is just delicious

Two minutes... yeah that's pretty good on the timing issue.

Still for that timeframe you would still need the Magic Circle caster to start at the same time. You'd want Magic Circle up 30 seconds before Banishment expired just to be sure (IMO) and since you can't quite be sure how long fighting anyone else there would take its still be a major commitment of two casters for one opponent.

Won't catch me trying this, but it might be crazy enough to work. :smallamused:
