Unstoppable Ram

You shape metal to shatter shields, gates, and even armor. Make a ranged spell attack against a target within range of the spell. If you hit an object that can be destroyed, it shatters automatically. If you hit a creature, it takes 12d10 crushing damage and becomes Unconscious for the next 1d4 hours. A creature can use its action to wake an Unconscious target affected this way.

If you hit a creature wearing nonmagical metal armor, the armor is destroyed. If the armor is magical, it becomes warped, taking a -2 penalty to its AC until it is repaired by a creature making a Strength check with smith’s tools against your spell save DC. A creature without proficiency in the Blacksmithing craft makes the check at disadvantage, and on a failure, the DC to repair the armor increases by +5.
