Terrarian adventurers have a lot of neat accessories to help them explore their world, but one of the highly coveted ones is the Propulsion Boots. These boots bestow the wearer with the ability to launch into the sky with impressive velocity. It's like having your very own private rocket propulsion system strapped to your feet! Equipping the rocket boots enables players to arrive at previously inaccessible altitudes, encouraging exploration easier. With these boots, Terraria becomes a true vertical adventure!
