Bottle of Tsunami (5e Equipment)
From D&D Wiki
Wondrous item, uncommon
A simple glass bottle with a miniature weather system inside; it is filled with gale-force winds and violently crashing waves. At any point during a jump movement, you may uncork the bottle and release a jet of water. When you do so, you make a second jump, using a Strength score of 12, in any direction and which doesn't cost any movement. If you are in water, as an action, you can use this item to push yourself 15 feet in any direction, including out of the water. You may also use this item as a reaction, negating fall damage. It takes 1d4+1 rounds for the waves in the bottle to reform and let you use this item again.
