Death's Touch

Muttering the phrase of arcane power, the caster takes 100 gold pieces in a pouch and pours a vial of their blood into the pouch over the gold and cast the spell.

A sphere of imploding negative energy ripples out in a 60-foot-radius sphere from a point within range. Each creature in that area must make a Constitution saving throw. A target takes 14d10 necrotic damage on a failed save, or half as much damage on a successful one.

Ritual casting this spell takes one minute.
