Timeless Step

You move effortlessly within the timeless eternity of the Feywild, your motions swift and deadly, while your enemies seem to crawl ponderously through time and space. You create an area of effect with a radius of 15ft that can last up to 4 hours. While you are in this area, all your attacks have advantage, and all attacks against you are at disadvantage.

You can also cast this during a long rest to decrease the required time in half to 4 hours to gain the benefits of a long rest.
