Cold fusion

You cause the surface of two objects which are touching to merge with each other on a molecular level, effectively gluing them together.

If a creature's skin is affected by cold fusion, they cannot detach from the object without taking 1d4 piercing damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher,  affected creatures need to make a strength check to detach from the object, and the damage increases by 1d4 for each slot level above 1.
