Bloodlink Bond

You establish a mystical bond between yourself and a target creature within range. The target must make a Wisdom saving throw. On a failed save, the creature becomes bloodlinked to you. While the bond is active, whenever the target deals damage to you, it takes psychic damage equal to half the damage dealt.

Additionally, you may end the spell early by performing a Bloodwalk, using a bonus action to teleport to the target creature’s location via their blood if they are within 60 feet of you. When you teleport in this way, the target must make a Constitution saving throw or take 6d10 necrotic damage on a failed save, and half on a successful save. When you perform your Bloodwalk, choose an unoccupied space within 5 feet of the target creature to reappear. If none exists, you are shunted to the nearest unoccupied space and take 10d10 force damage.
