Hermes Boots

Hermes Boots is an accessory that can be found as loot from Underground and Underground Jungle Chests.

These boots slightly increase the wearer's movement speed, and provide a large speed boost after running in one direction for a couple seconds, which lasts for as long as the wearer continues running in that direction. Movement speed of the player is conserved; jumping while running will not cancel the speed boost. If used along with a Cobalt Shield you will not lose the speed boost after getting hit by an enemy. The top speed from Hermes Boots can be reached quickly with the use of the Grappling Hook or the Ivy Whip. Simply grapple the ground before you (around 5-15 blocks) and then jump as you are getting pulled forward. Another way to instantly use Hermes Boots is to grapple the middle of a door and then open it. Continue running in the direction that you opened the door and you are now running at full speed!
