Unstoppable Charge

You become an entity that can no longer be stopped. You gain immunity to Thunder damage and cannot be shoved or knocked prone, and whenever you move at least 15 ft. in one direction, you can display a number of feats:

• You knock prone a huge or smaller creature, a gargantuan creature can make a Strength saving throw against your spellcasting DC or be knocked prone, a colossal creature has advantage on the save.
• You can break through a stone wall no thicker than 3 ft., you need to succeed on a Strength (Athletics) check (DC 10 + 5 for every ft. thicker than 3 ft.) to break through thicker stone walls. Non-magical trees, wooden walls and anything smaller than a tree do not impose any resistance to your movement.
• You can use a bonus action to dash. This is a special dash that adds double your movement speed, but you cannot dash with an action then.
• You gain advantage on your first attack roll with a melee attack, given that the creature is standing at the moment you roll for damage. You can only gain this benefit once per turn.
• Your long jump and high jump distance doubles, and you can make a standing long jump and high jump as if you had 30 ft. of movement beforehand.
