Weighted Step

You increase the local pull of gravity on a creature you can see within range. The target must succeed on a Strength saving throw or have its speed reduced by 10 feet for the duration.

Until the spell ends, the first time on each turn that the target moves more than 10 feet, it must spend 2 feet of movement for every 1 foot moved until the end of that movement.

The target can repeat the saving throw at the end of each of its turns, ending the spell on a success.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for every two slot levels above 1st.
