You point at one creature that you can see within range and attempt to transform the blood inside their body into searing flame. The target must make a Constitution saving throw. On a failed saving throw, the target takes 8d6 necrotic damage and 8d6 fire damage and is set internally ablaze until the spell ends. On a success, the target takes half as much damage and is not set ablaze.   At the start of each of its turns while it is internally ablaze, the target takes 8d6 necrotic damage and 8d6 fire damage and becomes poisoned until the end of its next turn. While poisoned in this way, it is also stunned.   A creature set internally ablaze by this spell must make another Constitution saving throw at the end of each of its turns. If it successfully saves against this spell three times, the spell ends. If it fails saves three times, it instantly takes 8d6 necrotic damage, the spell ends, and the transformation becomes permanent -- a magical effect lingers inside its body. It is incurably poisoned and takes 8d6 fire damage at the start of each of its turns until it dies. The successes and failures don’t need to be consecutive; keep track of both until the target collects three of a kind.   A dispel magic spell can end the permanent effect only if it is cast as a 9th-level spell.   A creature that dies while affected by this spell or by the permanent magical effect is reduced to ashes. The spell has no effect on a creature that doesn't have blood. This spell is also a Blood spell in addition to its other school.
