You attempt to turn one creature or object that you can see within range into a single crystalline form. If the target is a creature, it must make a Constitution saving throw. On a failed save, it is restrained as its body begins to crystallize. On a successful save, the creature isn't affected.

A creature restrained 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 its saves three times, it is turned into a single crystal and subjected to the petrified condition for the duration. The successes and failures don't need to be consecutive; keep track of both until the target collects three of a kind.

While restrained by this spell, the creature or object is vulnerable to bludgeoning, force and thunder damage.

If the creature or object suffers any bludgeoning, force or thunder damage while petrified, it shatters into millions of crystal shards and is irrevocably destroyed. A creature destroyed in this fashion cannot be returned to life by anything short of a wish spell.

If you maintain your concentration on this spell for the entire possible duration, the creature or object is turned into a single crystal until the effect is removed.
