This iron bottle has a brass stopper. You can use an action to speak the flask's command word, targeting a creature that you can see within 60 feet of you. If the target is native to a plane of existence other than the one you're on, the target must succeed on a DC 17 Wisdom saving throw or be trapped in the flask. If the target has been trapped by the flask before, it has advantage on the saving throw. Once trapped, a creature remains in the flask until released. The flask can hold only one creature at a time. A creature trapped in the flask doesn't need to breathe, eat, or drink and doesn't age.
You can use an action to remove the flask's stopper and release the creature the flask contains. The creature is friendly to you and your companions for 1 hour and obeys your commands for that duration. If you give no commands or give it a command that is likely to result in its death, it defends itself but otherwise takes no actions. At the end of the duration, the creature acts in accordance with its normal disposition and alignment.
An identify spell reveals that a creature is inside the flask, but the only way to determine the type of creature is to open the flask. A newly discovered bottle might already contain a creature chosen by the GM or determined randomly.

Posted Sep 15, 2019Would this work on Tiamat or the Tarrasque if you polymorphed them into something weaker?
Imagine capturing Tiamat, then having her as your pet for 50 minutes and then telling her to go back into the flask, only to be used again. Probably not RAI. Oh well.

Posted Feb 3, 2020Yeah the goal would be burning through their legendary resistances and then trying to get a polymorph to stick so they'd fail the save that would suck them into the flask.

Posted Apr 20, 2020Not necessarily. After the creature is let out, they get advantage on avoiding being put back in, and even a creature friendly to you is unlikely to get back in the flask willingly. A planetar has a really high bonus to Wisdom saves, so with advantage it's very unlikely to get back in. There's nothing that makes them return, so you got to try to trap them again, and messing with an angel can have dire consequences. So most of the time it's a one use strong monster until they meet something else from a different plane.

Posted May 23, 2020Could a Devil use one of these on a PC they find fooling around in Avernus?
This is presuming the PC isn't a native to the Nine Hells themselves, which is fairly unlikely.

Posted May 26, 2020Shouldn't they all contain Djinni? I mean, let's be realistic here, folks! On a serious note here, what do you think would be the best creature to put inside to surprise/scare the pants off a party? Speaking of parties, you could bury it in a cake and have a Night Hag pop out on someone's birthday. Again, I digress.

Posted Oct 17, 2020It obeys your commands though, and you can just command it to go back in the flask. That doesn't result in its death. So you basically just command it back in after every 55 minutes or so.

Posted Jan 28, 2021I'd rule that you cannot command a creature to go back into the flask. The only way for a creature to go into the flask is as described: you target the creature, and it makes a saving throw. They don't state it, but I'd say that once a save has been made, the creature is immune to the flask. I'd also say that if the flask cannot have a new inhabitant until that 1 hour is up. Also, I'd make this attuned. But that's just me! (I'd also make sure the PCs know that my Iron Flask limitations are unique to the flask which they found, and make the limitations known from the outset so no-one gets all a-fluster!)
