Weakening

You affect the body of a creature that you can see within range, attempting to shatter its body. The target takes 4d6 necrotic damage and must make a Constitution saving throw.

On a failed save, the creature's Strenght, Dexterity and Constitution scores become 1. The creature can't push, drag, or lift any object. The creature can, however, walk, but it's speed is reduced to 5 ft.

At the end of every 30 days, the creature can repeat its saving throw against this spell. If it succeeds on its saving throw, the spell ends.

The spell can also be ended by greater restoration, heal, or wish.
