Valravn

You magically call forth a raven that begins to feed upon a corpse of your choice that you have sprinkled with salt. Upon eating it, the raven then transforms into an armored humanoid warrior adorned with raven-like features, such as a cloak of raven feathers, a pointed and drooping nose, and raven-like eyes, and appears in an unoccupied space within 10 feet of the corpse. This warrior, known as a Valravn, assumes the statistics of a knight, with the following change: the knight's Leadership ability is instead replaced with the following feature:

Aura of Doom (3/day). As a reaction to when a creature within 30 feet of the valravn that is hostile to you, the valravn, or an ally makes an attack roll, the valravn can utter a string of phrases in an obscure tongue consisting of raven caws and calls. The creature must then subtract a d4 to its attack roll, provided it can hear the valravn.

The valravn disappears when it drops to 0 hit points or when the spell ends. It is friendly to you and your companions for the duration. Roll initiative for the valravn, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the valravn, it defends itself from hostile creatures but otherwise takes no actions.

If your concentration is broken, the valravn resumes its original form as a raven and flies away. The GM has the valravn's statistics (knight).

Finally, when you cast this spell, the warrior can aesthetically resemble in some way a humanoid that you had known who had died.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, you can create one additional valravn for every other slot level above 4th. Each raven that turns into a valravn can feed on the same corpse.
