Wondrous Item

Legendary Requires Attunement

A majestic Feystag horn, carved with elvish prayers. When blown, it signals the start of the Wild Hunt.
Companion Manifestation: You may use an action to blow into this horn, causing one of your familiar spirits to manifest more completely in the material world.
Add your proficiency bonus to the beast’s AC, attack rolls, and damage rolls, as well as to any saving throws and skills it is proficient in.
The beast obeys your commands as best as it can. It takes its turn on your initiative. On your turn, you can verbally command the beast where to move (no action required by you). You can use your action to verbally command it to take the Attack, Dash, Disengage, or Help action. If you don’t issue a command, the beast takes the Dodge action. Once you have the Extra Attack feature, you can make one weapon attack yourself when you command the beast to take the Attack action. While traveling through your favored terrain with only the beast, you can move stealthily at a normal pace.
If you are incapacitated or absent, the beast acts on its own, focusing on protecting you and itself. The beast never requires your command to use its reaction, such as when making an opportunity attack.
Each Manifestation has a different Statblock, and is unlocked at different levels of Devotion to Myrmidia.
You may Manifest any companion you have unlocked, regardless of your current Hunting Path. Once you do so, you cannot do so again until you complete a Long Rest.
