Pocket Oasis

Wondrous item, very rare

When you throw this 5-foot-by-5-foot square of black cloth into the air as an action, it creates a portal to an oasis hidden within an extradimensional space. A pool of shallow, fresh water fills the center of the oasis, and bountiful fruit and nut trees grow around the pool. The fruits and nuts from the trees provide enough nourishment for up to ten Medium creatures. The air in the oasis is pure, cool, and even a little crisp, and the environment is free from harmful effects. When creatures enter the extradimensional space, they are protected from effects and creatures outside the oasis as if they were in the space created by a rope trick spell. The effect lasts for 24 hours or until all the creatures leave the extradimensional oasis, whichever occurs first. Any creatures still inside the oasis at the end of 24 hours are harmlessly ejected. Once used, the pocket oasis cannot be used again for 24 hours.
