Featherfall Potion

The Featherfall Potion is a buff potion which grants the Featherfall buff when consumed. The buff reduces the player's fall speed and gravity by 1/3, allowing them to jump higher than normal.

The player can hold the key to cancel the effects or the  key to further reduce fall speed and gravity to 90%. While under the effects of both Featherfall Potion and Gravitation Potion, holding the key will make the player fall up at normal speed. The player will fall up at a slowed speed when holding no direction.

The effects of the Featherfall Potion can also be used to jump higher. By holding, grappling a platform above you, and releasing the grapple before it is complete, one may achieve jumping heights of several hundred blocks.

Fall damage is also negated, even when falling normally. It is worth noting that the Featherfall Potion also increases the distance players are knocked back when hit by an attack.
