Constrict Metal

Choose a manufactured metal object that is worn on the target, such as a suit of heavy or medium armor, that you can see within range. You cause the object to visibly constrict and crush inwards on itself. The target creature that is wearing the object, must make a strength Strength saving throw. If the target fails, it takes 1d8 Damage. The creature also loses half it's movement, and has disadvantage on Acrobatics or Athletics checks until it succeeds on a Strength saving throw, or the spell ends. The creature can repeat the saving throw at the end of each of it's turns.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
