Very Rare Wondrous Item (Parasol), Requires Attunement

Nightwalker’s Salvation. While you are holding this big magic parasol above you in at least one hand, you cannot negatively be affected by sunlight in any way.

Each time a creature is charmed or frightened while within the area, the shadows inside parasol feed on their emotions and you regain 2d6 Hit Points
While the item is on the same plane of existence as you, you can use your action to make it appear in your hand. 

Eclipse. Once per long rest as an action, you can raise the parasol and make it start flying upwards. After reaching its apex, it will create a 30-foot radius dome of darkness around and above you. The border of the dome is a 5-foot thick wall with the properties of the darkness created by the Darkness spell.
