You speak an unforgivable curse that causes waves of intense pain to assail one creature you can see within range. The target must make a CHA saving throw or be subject to intense torture.

While the target is affected by Crucio, any speed it has can be no higher than 10 feet. The target also has disadvantage on attack rolls, ability checks, and saving throws, other than CHA saving throws. Finally, if the target tries to cast a spell, it must first succeed on a CON saving throw, or the casting fails and the spell is wasted.

A target suffering this pain can make a CHA saving throw at the end of each of its turns. On a successful save, the spell ends.
