Hydaelyn

You cast a hex on a creature you can see within range. The target must succeed on a Charisma saving throw or take 3d4 force damage and have their speed reduced by 30 feet for 1 minute. On a successful save, the creature takes half damage and suffers no additional effects. At the end of each of its turns, the creature can reattempt the saving throw to end the hex on a success. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st and you target an additional creature for each spell level above 1st.
