Royal Scepter

The Princess only moves in once your town is essentially finished, so this is a late unlock and a bit of a victory lap. It is also one of the very few cosmetics your character physically carries. Almost everything else in the game sits on your head or your body, so a prop held in hand stands out in a screenshot.

Put it in a social accessory slot. It cannot be reforged and it gives nothing, so a functional slot is pure waste.

Your character can only hold one thing at a time, so the moment you swing a weapon the scepter detaches and hovers next to you instead of staying in your grip. The game files also class it as a balloon, which changes nothing you will ever notice and is just a leftover of how it was put together.
