Amulet of the Umbra

This amulet bears the symbol of the Umbra diety inlaid with a carving of circles and triangles, framing a sun, the moons, and the space around it. While you have the holy symbol equipped, you gain a +2 bonus to your attack rolls and saving throws. 

This item has 3 charges. You can choose any of the one effects.

1. A shadow comes up in front of you as a shield, blocking you from damage. As a reaction, if taking damage, you can cast the Shield spell.
2. You can select up to five creatures to receive temporary hit points equal to your current level + your proficiency bonus.
3. Shadows bend and swirl at your feet, and shroud you in a cloak. All attacks against you have disadvantage until the start of your next turn.
