fathom crater
Have it to where after beating the “Hello Guest” Side Quest in the Banner a New Tool Kit would get added with the Hammer and a Crate with limited Boards (Maybe 3-6) to make it fair, while you could say this is unfair for the AIs, they are all getting Bashing Mechanics like The Guest soon so they could simply use that.
This would be great as it means you gain something useful out of doing something else during the Main Game.
