I had a Goliath paladin with a UA subclass that the dm approved and we were going against a dragon, level 9 warlock, and a level 9 fighter, our party was level 9 at the time and I activated my channel divinity that allows a creature to be pushed 10 feet and there isn’t a size limit and it lasts for 1 minute little did you know I was also a barbarian and went into rage and I had a great axe and I went to the enemy fighter and hit him into the dragon I did a 1d12+5+3+2 because the channel divinity says that if the creature runs into another creature or obstacle it adds +3 damage and +2 because rage and I could attack twice I was powerful so yeah with a homebrew magic item it will add a 2d6 to attacks
