During the massacre of the Martikov House, you were infected by the blood of your dying lycanthropic sibling and inherited their curse by blood. 

An infected wereraven of the Martikov House has certain rules they live by, which are as follows: 

• Do not allow anyone to touch your blood. 
• If you are becoming emotional, excuse yourself until you can calm down. 
• Do not kiss anyone or engage in any intimate contact impulsively. 

Dexterity Increase. Your Dexterity score increases to 16, if it was not already 16 or above.

Superior Darkvision. You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray. During the full moon, you can see in darkness as if it is daytime. 

Immunity to Poison. You are immune to being poisoned and cannot become inebriated.

Animal Communication (Ravens). You have the ability to speak and communicate with ravens. 

Immunity to Polymorph. You are immune to the Polymorph spell and condition.

Magical Damage Healing. You cannot heal magical (or silvered) damage done to you without magical intervention.

Wind Sensitivity. You have a sensitivity to wind currents and changes in air pressure, which can be helpful at finding drafts, detecting movement and changes in the weather.

Regeneration. The wereraven regains 10 hit points at the start of its turn. If the wereraven takes damage from a silvered weapon or a spell, this trait doesn't function at the start of the wereraven's next turn. The wereraven dies starts making death saving throws only if it starts its turn with 0 hit points and cannot regenerate.

Increased Breath Capacity. You can hold your breath for twice as long as a regular human. 

While transformed, the following features apply: 

Shapechanger. The wereraven can use its action to polymorph into a raven, or back into its human form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its human form if it dies.

Flyby. You do not incur opportunity attacks when you fly out of an enemies’ reach. This ignores the Sentinel feat.

Mimicry. The wereraven can mimic simple sounds it has heard, such as a person whispering, a baby crying, or an animal chittering. The wereraven has advantage on deception and persuasion checks while mimicking the voice of someone it has heard before.
