You attempt to turn one creature that you can see into stone.

If the target's body is made of flesh, the creature must make a Constitution saving throw, potentially becoming

Restrained

Petrified

Critical Success (+10). The target is unaffected.
Success. The target is Restrained until the end of its next turn.
Failure. The target is Restrained for the duration of this spell. While it is Restrained by this spell, it must make another Constitution saving throw at the end of each of its turns. If it successfully saves against this spell two times, the spell ends. If it fails its saves two times, it becomes Petrified for the duration. The successes and failures don't need to be consecutive. If you maintain your concentration on this spell for the entire possible duration, the creature is Petrified indefinitely until this effect is removed.
Critical Failure (–10). As failure, except the target only needs to fail one more Constitution save to become Petrified, and if so, they are Petrified indefinitely until this effect is removed.
