You learn the tiny hut spell and can cast it once a day without expending any spells slots and without requiring material components. This spell possesses all of its usual characteristics, however you can also create a hearth, mantle or fire place within the tiny hut. You can control the appearance of this addition, it can be as opulent or as humble as you desire. However it is essentially illusory, in that you cannot remove any aspect of it from the tiny hut and it possesses no real value.
