Collective Demise

You weave a complex ritual that binds the souls of multiple creatures together, creating a powerful nexus of necrotic energy. Choose up to three creatures within range. Their souls become intertwined, sharing damage and effects until the spell ends. While concentrating on the spell, any damage dealt to one of the affected creatures is divided equally among all creatures linked by Soul Convergence. Additionally, any ongoing magical effects affecting one linked creature affect all linked creatures. If one of the linked creatures dies, the spell ends immediately. Affected creatures do not share healing. E.g. If one creature is healed by a cure wounds spell, they are the only one to benefit from that.
