I'm sure you know which one I'm talking about.
The Demon King, while in Zeldris's body, turned a hill and a house into a meatball by flexing his powers. Note that this was while he was getting used to his new vessel.
Could this be used as a feat in vs threads? If so, where would one place feat at? Do you think he can turn bigger things into meatball the same way?
