Crystalize

Choose a point on the ground or a solid surface within range. Crystals rapidly form in a 5 foot radius sphere and any creature caught in that space must make a dexterity saving throw or become restrained until the spell ends. A creature can use their action on their turn to make a strength check, freeing themselves on a success.

If the crystal structure or anyone caught inside take bludgeoning, piercing, slashing, force or thunder damage, the crystals explode into razor sharp shards. Any creature restrained by the spell or within its area of effect must make a dexterity saving throw or take 1d6 piercing damage, and the spell ends. The crystals will also explode in this way when a creature successfully breaks free from them, if a creature moves through their space, or if the spell ends early.

if you cast this spell at higher levels, the damage increases by 1d6 per level.
