The Symbol of Ravenkind

The Symbol of Ravenkind was a magical item discovered by our heroes in the garden of the Abbey of St. Markovia, following Osrin's recollection of a prophecy from Madam Eva. This version of the Symbol of Ravenkind is adapted from MandyMod's Fleshing Out Curse of Strahd guide.
In order to secure the symbol, our heroes had to do battle with several wights in the livery of Castle Ravenloft who had seemingly been tasked with guarding the item so it could not be used to harm Strahd von Zarovich.
Once the wights had been destroyed, Ri-An used their magical abilities to identify the item, which allowed them to learn the following properties:

• This item is legendary and requires attunement.
  • Specifically it requires attunement by specific types of people, though Ri-An seemed unable to fully put the requirements into words; however, they were able to communicate that only someone with good intentions and a strong moral code would be able to use it effectively.
• The symbol can hold up to 10 charges, regaining 1d6+4 used charges every day at dawn.
  • Mental Barrier. Anyone who wears the Symbol of Ravenkind and is attuned to it gains the benefits of a nondetection spell, and is immune to psychic damage. As an action, the wearer can expend 2 charges to project this effect in a 15-ft radius around themselves, protecting any other creature within range. This effect lasts for one hour..
  • Raven's Eye. As an action, you can expend 3 charges to magically animate 1d4 swarms of ravens to aid you in combat. When combat ends, the summoned ravens burst into feathers and disappear..
  • Sunlight. As an action, you can expend 5 charges while presenting the Symbol to make it shed bright light in a 30-ft radius and dim light for an additional 30 ft. The light is sunlight and lasts for 10 minutes or until you end the effect (no action required).
