Ancestral Spirit Guardian

Shared Senses. The ring bearer shares vision and hearing with the Ancestral Spirit Guardian.

Mystical Regeneration. As the spirits physical form is created from the ring bearers magical energy, its form can be restored if destroyed or banished. Once per short rest, as a bonus action, you can sacrifice a spell slot to instantly restore your spirit guardians body, causing it to reappear in a space within 10 ft of you and restoring its hits points by (1d8 + 4) x the sacrificed spell slots level.

Guardian of the Bloodline. If the ring bearer would suffer a fatal blow while within 60 ft of Ancestral Spirit Guardian, the spirit guardian is destroyed instead, and the ring bearer recovers hit points equivalent to the hit points the Ancestral Spirit Guardian had remaining when destroyed. This can only occur once per long rest and the spirit cannot be regenerated via Mystical Regeneration when destroyed this way.

Sapping Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 6 (1d4 + 4) piercing damage, and the target must make a Constitution saving throw (DC = Ring bearers spell save DC), taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one. Additionally, the creature subtracts (1d4) from the next attack roll or saving throw it makes.

Cursed Constriction. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 4) bludgeoning damage, and the target must make a Strength saving throw (DC = Ring bearers spell save DC), or become grappled. While grappled, the creature is restrained and cursed, causing it to take an additional die of damage from all sources.
