Raven Sight:

3 times per day, as an action the wearer can call a spectral raven from the necklace. The raven rises from the necklance as a shadow form and coaleses into a semi-corpeal creature nearly indistinguishable from an actual raven. The raven becomes your eyes and ears while using this ability. you can no longer percieve your own senses, becoming blind, def, and incapacitated, but your perception through the beast includes and special senses the beast may have. You may end the link early unsing your action to regain your own senses. When this happens the form of the raven disappears into the shadows. Any damage to the raven also causes it to disipate into shadow, ending the ability

Raven Shape

at 6th level (requires attunment) the consistan use of the Ravensight necklace has created a link between the wearer and the shadow. You can use you action to magically assume the semi-corporeal shape of the raven. You can use your action to end the ability or suffer damage and fail a concentration check. You regain expended uses when you finish a short or Long rest.

The Shadow Raven has all the stats and abilities of a common raven except hit points. In Raven Sight any damage disipates the form. In Raven Shape the raven effectively has the wearer's hit poins and disipates if you take damage and fail a concentration check
