You unleash a necrotic contagion magic on a creature you can see within range. The target makes a Constitution saving throw. On a failed save, it takes 14d6 Necrotic damage, and its Hit Point maximum is reduced by an amount equal to the Necrotic damage it took. On a successful save, it takes half as much damage only. This spell can’t reduce a target’s Hit Point maximum below 1. The Contagion remains for 10 Minutes though the damage is only taken once.
If another creature attempts to assist the target and touches them during the 10 Minute period, they must make a Constitution saving throw or take 7d6 Necrotic damage and their Hit Point Maximum is reduced by an amount equal to the Necrotic damage it takes. If the save is successful they take no damage. The contagion will last a further 10 Minutes on this creature and if touched the contagion will spread again with 3d6 Necrotic damage. A successful Constitution save will end the contagion.
