Bromn's Anchored Grip

Your magic anchors a creature to the ground, preventing it from moving or being moved.

You choose a target creature that is touching the ground. The target must succeed on a Strength saving throw, or its movement speed is reduced to 0 feet for the spell’s duration (a creature can willingly fail their save). Also, while affected by this spell, any action or effect that attempts to physically move the target automatically fails.

At the beginning of the creature's turn, it can attempt another Strength saving throw to escape the effect.

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