Blood to stone.

You fire a bolt of crimson energy at a creature within range. The creature must make a constitution saving throw or its blood magically begins to turn to stone and the creature is stunned until the end of its next turn. It must repeat the saving throw at the end of its next turn. On a success, the effect ends. On a failure, the creature is ripped apart as its blood solidifies and bursts out through its skin. This spell has no effect on creatures that do not have blood to lose. With an ooze or ooze - like creature this spell instead petrifies it until it is freed by a greater restoration spell or greater magic.
