Storm Diver's Additions Mod/Heavy Boots

The Heavy Boots are a prehardmode accessory crafted from rocket boots and an anvil. While in the air holding down greatly increases fall speed and acceleration, and creates a damaging shockwave upon impacting the ground. While falling at the fast speed you are immune to knockback and damage any enemy you fall through.

Trivia

 * Despite being crafted from rocket boots, they do not give the ability to fly, this is somewhat referenced in the tooltip.
 * This is the only item that requires a crafting station in its recipe.
