You blast a creature within range with a beam of pure, entropic energy that ages it rapidly. The target takes 4d6 necrotic damage and must make a successful Constitution saving throw; on a failure, its Strength and Dexterity are both reduced to 1. While its Strength and Dexterity are reduced in this way, the creature can’t hold weapons weighing more than 3 pounds, its speed is halved, and it can’t take reactions. The creature’s Armor Class and attack rolls are modified to account for its reduced attributes. The creature can cast spells normally.
