Terrarian adventurers have a lot of neat accessories to help them scout their world, but one of the highly coveted ones is the Propulsion Boots. These boots provide the wearer with the ability to blast off into the sky with great speed. It's like having your very own personal rocket propulsion system strapped to your feet! Using the rocket boots enables players to get to previously inaccessible altitudes, fostering exploration more manageable. With these boots, Terraria becomes a true vertical adventure!
