Casting Time 10 minutes
Range Self
Components V, S, M (a small silver cup filled with the caster’s blood)
Duration 12 hours
Classes Cleric, Sorcerer, Warlock, Wizard
You fill a small silver cup with your own blood (taking 1d4 piercing damage) while chanting vile curses in the dark. Once the chant is completed, you consume the blood and swear an oath of vengeance against any who harm you.
If you are reduced to 0 hit points, your oath is invoked; a shadow materializes within 5 feet of you. The shadow attacks the creature that reduced you to 0 hit points, ignoring all other targets, until it or the target is slain, at which point the shadow dissipates into nothing.
When you cast this spell using a spell slot of 5th level or higher, an additional shadow is conjured for each slot level above 4th. ***Ritual Focus.*** If you expend your ritual focus, the spell summons a banshee instead of a shadow. If you also use a higher-level spell slot, additional undead are still shadows.
