The 水上漂药水 is a 增益药水 which grants the 水上漂 增益 when consumed. The buff allows players to walk on 水 and 熔岩. The player can sink in the liquid by pressing down. This lasts for 5 minutes, but can be cancelled at any time by right-clicking the icon.
Despite the description, players are also able to walk on lava without damage and without the need for the 黑曜石皮药水. This makes it a viable alternative to Obsidian Skin Potions when traversing the 地狱, as the ingredients required are generally safer to obtain (though more time-consuming to gather in bulk). Players should still take care when dropping long distances onto 熔岩, as they may find themselves partially submerged and take damage from the 熔岩.
- The 熔岩靴 accessory does everything the potion does and more. The Water Walking Potion still can have use, if you wish to walk on water without giving up an accessory slot.
