Circle of Zul'med

You create a stationary, magical circle with a 10-foot-radius circle around yourself that enriches your aura while you are within it. Until the spell ends, you have advantage on Charisma and Wisdom checks you make against other creatures within the circle. The magical circle lasts until you leave it or if it is dismissed by other magical means. 

In addition, whenever you complete a short or long rest while meditating within the circle, you gain temporary hit points equal to one roll of your hit dice. During a short rest, you must be undisturbed while meditating for the entire rest or you do not gain any temporary hit points. During a long rest, you must spend at least one hour doing the same to receive any benefits.
