Aether

When you drink this potion, which appears as an icy blue liquid, you gain immunity to cold damage for the next 8 hours. While immune in this way, any water you step on turns to ice, allowing you to walk over it. For 2 hours after these effects end, your walking speed is halved and you have disadvantage on Dexterity checks and Dexterity saving throws.
