Siege

You have mastered the art of breaking things with brute force. All attacks that deal bludgeoning, piercing, or slashing damage ignore immunities and resistances to those types when damaging objects, constructs, and undead. 

In addition, any unarmed or melee weapon attack does double damage to structures.

You have advantage on any strength check that is based on breaking an object (kicking down a door, etc.), the DM has final say on what this entails.
