You reach into the Aetherweave and draw forth light and heat. Until the spell ends, a bright ball floats on a string tied to your body. The ball sheds bright light in a 10-foot radius and dim light for an additional 10 feet. The light can be colored as you like. This spell does not require a source of Aether to cast.

While the Float Flame remains, you are protected from the harsh elements of cold weather, and do not require special clothing or equipment to survive in arctic climates.
The spell ends if you cast it again or dismiss it as an action.
