Your patron is the Raven Queen, a mysterious being who rules the Shadowfell from a palace of ice deep within that dread realm. Her ability to reach into the world is limited. Thus, she turns to mortal warlocks to serve her will. She concerns herself with ensuring that those fated to die pass from the world as expected, and bids her agents to defeat those who seek to cheat death through undeath or other imitations of immortality.

The Raven Queen lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

At 1st level, you learn the spare the dying cantrip. It counts as a warlock cantrip for you, but does not count against your number of cantrips known.

Sentinel Raven

Starting at 1st level, you gain the service of a spirit sent by the Raven Queen to watch over you. The spirit assumes the form and game statistics of a raven, and it always obeys your commands, which you can give telepathically while it is within 100 feet of you.

While the raven is perched on your shoulder, you gain darkvision with a range of 30 feet and a bonus to your passive Wisdom (Perception) score and to Wisdom (Perception) checks. The bonus equals your Charisma modifier. While perched on your shoulder, the raven can’t be targeted by any attack or other harmful effect; only you can cast spells on it; it can’t take damage; and it is incapacitated.

You can see through the raven’s eyes and hear what it hears while it is within 100 feet of you.

In combat, you roll initiative for the raven and control how it acts. If it is slain by a creature, you gain advantage on all attack rolls against the killer for the next 24 hours.
