Devilicus' Ram

You create a shimmering object known for causing large impacts (such as a bull, or battering ram) that barrels forward towards an enemy or another object.  If the object hits an enemy, it lasts for the duration, until the target escapes the grapple, or until the spell is dropped.  If the object hits another object, it disappears after impact.  If the object misses it's target, it disappears.

On impact, the target takes 2d6 bludgeoning damage plus your spell casting modifier.  If the target is a creature of no more than one size category over you the creature is immediately grappled and pushed 20 feet directly away from you.  On subsequent turns, you may use a bonus action to continue to push the enemy another 20 feet dealing an additional 1d6 bludgeoning damage.  If the enemy is pushed directly into a solid surface (such as a wall), the enemy takes an additional 2d6 bludgeoning damage.  On the target's turn, they may attempt to break the grapple with a contested athletics or acrobatics check against your spell casting modifier.  If the target is an object, the attack is an automatic critical hit.

At Higher Levels.  When you cast this spell using a spell slot of 3rd level or higher, the damage from the initial casting of the spell increases by 1d6 and the push increases by 5 feet for each slot above 2nd.
