Restless

Through practice, adaptation, or possibly just nature you no longer require proper sleep to function. Instead to gain the benefits of a long rest, you only need to do 8 hours of relatively light activity- such as reading, cooking, or keeping watch. During this time, you may also cast one spell of 1st or 2nd level as a ritual without interrupting your rest if you have the Ritual Casting feature already. Magic and other abilities can still put you to asleep, however.
