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 grant the wearer with the ability to ascend into the sky with great speed. It's like having your very own personal rocket propulsion system strapped to your feet! Wearing the rocket boots enables players to reach previously untouchable heights, encouraging exploration easier. With these boots, Terraria becomes a true vertical adventure!
