Word of Wounding

You speak a word of magical force that wounds the target. The target takes 1d4 force damage and must make a constitution saving throw or have its movement speed reduced by 5 ft. until the end of its next turn. If the target succeeds then it's speed is not reduced but it takes the damage.

At level 11 you may target one additional creature per casting of this spell.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
