Constellation of the Hunt

The Wolf Who Stalked The Stars. Your struggle with the Elder of Beasts has left you with a loyal companion whose fangs and claws you may call upon. Once the source of your Hunter's Curse, it is now a source of divine strength all to your own. As an action, you may call forth an avatar of the Elder of Beasts to aid you in combat (tarrasque statblock). Fenrir shares your initiative count and will follow your will without question. It may benefit from all of your class features and you may cast spells as though they originated from Fenrir's location. Whenever Fenrir is summoned, if you were to take damage, you may instead have Fenrir take that damage for you. Being bonded to you by both blood and divine bonds, Fenrir uses your armor class and saving throws and shares your damage resistances and immunities. When out of combat, Fenrir shrinks down to a smaller size, appearing as a wolf. It will remain with you during the day before vanishing at night into a swirl of starlight. If Fenrir is ever killed, destroyed, or otherwise removed, you must wait 6 hours to manifest it again as it requires recuperation within your own soul.
