This barrel has an interior space considerably larger than its outside dimensions, with a removable top and bung hole. The barrel can hold up to 500 gallons of any liquid. There is no way to keep these liquids separate and pouring several different liquids will cause them to mix together into what is often called a "Holding Brew" . The barrel weighs 30 pounds, regardless of its contents. You can spend an action to pour up to 6 gallons of liquid out of the barrel. If the barrel is already upside down, it will pour 6 gallons of liquid per turn, and prevents the person holding it from taking actions requiring hands. (Spells requiring somatic components or attacking with a weapon for example)
If the Barrel is pierced, or torn, it ruptures and is destroyed, and its contents are emptied in the Astral Plane. If someone attempts to pour liquid higher than the capacity of the Barrel, it simply will not go in, as if being poured onto a solid surface. If the barrel is turned upside down without its cap, its contents spill forth at a rate of 1 gallon per second (or 6 gallons per turn). Breathing creatures inside the bag can survive a number of minutes equal to 10 divided by the number of creatures, assuming the Barrel is free of liquid. If the barrel has liquid inside, subtract 1 minute from the total 10 per 50 gallons inside before dividing among creatures.
Placing a Barrel of Holding inside an extradimensional space created by a Bag of Holding, Portable Hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can’t be reopened.
