Potentially, yes. For whatever it’s worth to you, rules designer Jeremy Crawford has ruled that a bag of holding can be opened from the inside.
Where does the bag of holding go?
Astral Sea
Each bag weighs fifteen pounds, regardless of the contents within it. According to Allura Vysoren, who used to occupy her time by making bags of holding, when such a bag is destroyed (for example, by placing one bag into another), its contents are jettisoned into the Astral Sea.
What happens if you put water in a bag of holding?
The space inside the bag is described as a continuous finite volume, not a set of pocket-spaces for each individual item put in it; therefore, putting/letting water into it would get water on any other items sitting inside. * How quickly depends on the local water pressure, but just “quickly” is plenty of precision for our purposes.
What happens when you open a bag of holding?
When you are underwater its best to treat the water itself like air when it comes to taking up space. It will fill the bag when you open it, but it doesn’t affect its capacity until you cross over onto land again where you’ll have to dump the water out.
What’s the difference between a bag of holding and exploding?
There is no fundamental difference between it filing with water and exploding and filling with air and exploding. It is absolutely clear that the whole point of a bag of holding is that normal physics don’t apply and that it’s a convenient in-game way to be able to carry lots of stuff.
Can a bag of devouring empty an ocean?
Thus the Bag of Devouring (and thus the extradimensional creature it is linked to) is literally drinking the ocean. Using this rule, the bag could consume, at most, a volume equal to the largest creature size we have rules for (gargantuan) per turn. Using the house rules, how long would it take?
