Smoke leaks from the lead-stoppered mouth of this brass bottle, which weighs 1 pound. When you use an action to remove the stopper, a cloud of thick smoke pours out in a 60-foot radius from the bottle. The cloud's area is heavily obscured. Each minute the bottle remains open and within the cloud, the radius increases by 10 feet until it reaches its maximum radius of 120 feet.
The cloud persists as long as the bottle is open. Closing the bottle requires you to speak its command word as an action. Once the bottle is closed, the cloud disperses after 10 minutes. A moderate wind (11 to 20 miles per hour) can also disperse the smoke after 1 minute, and a strong wind (21 or more miles per hour) can do so after 1 round.
Notes: Control, Utility, Deception
Yes, this is magical smoke and you can breathe in it just fine. Items and spells do what they say and no more.
Yes, this is easily countered with Dispel Magic as you target the cloud effect, not the bottle. You will certainly be able to see the cloud, whether in it or outside it. The cloud IS what is obscuring your vision if you are within it. It is the ONLY thing you can see. ;-)
Finally reactivating this requires TWO additional actions, which makes using this in combat an easily countered one-trick pony.
Still a great tactic, but not one I would use when there is an enemy spellcaster around, and this is not always obvious at the start of combat, where you most likely would want to use this.
This works MUCH better as a get-away device.
It is made of Brass. It will go ding, ding, ding....
If the bottle is still open and inside the cloud, would a strong wind be able to disperse the cloud of smoke? In paragraph 3 it says that the cloud remains while the bottle is open, which is why I think that the wind will not dissipate.
Now THAT is one wicked idea, though I suppose since the smoke from the bottle is infinite, unless you have a similarly infinite source of poison, it would likely require special construction in order to disperse a high enough quantity to affect individuals.
Now im thinking of a Yuan-Ti Pureblood who is ambushing people in the area of poisonous smoke.
Despite the picture making it look like it's glass, the bottle is described to be brass, so it'd be rather tricky to simply smash it on the floor. And if ya somehow did damage it (magic items are typically extra resistant to any form of destruction, so good luck doing that), I would assume that a destroyed magic item would simply loose it's magic and do nothing (the last sentence of the Mending cantrip's description would imply that destroyed magic items become non-magical).
How did you smash a brass bottle?
But the smoke isn’t magical.
