The Gravitation Potion is a buff potion which grants the Gravitationbuff when consumed. This buff allows the player to invert gravity with ▲ Up making the screen appear upside-down, fall upwards, and walk on top of the ceilings. The effect can be toggled while in midair.
This lasts for 3 minutes, but can be canceled at any time by right-clicking the icon (), by selecting the icon and canceling it in the equipment menu (), by double-tapping the buff icon (), or by canceling the buff from the buffs screen ().
Falling to a map's height limit will automatically flip the player right-side up.
In the Old-gen console version, there is the option to turn off "World Flips Upside Down", making it so only the player flips.
While flipping gravity on Old-gen console version and using the Hoverboard's horizontal speed boost while having Hermes Boots or any equal or upgraded version equipped will cause the boots speed boost to allow the user to run forever. If using the Hoverboard's fixed hover mode then the user will stay in place forever.
Fishing is possible on reverse gravity; the fishing bobber will fall "upward" into the water. However, golf cannot be done on reverse gravity; the player will not even be able to swing the club.
Players falling upwards will not be stopped by most platforms, and will instead fall through them. Hammering a platform three times will allow the player to "land" on it upside down, but this usually does not reset the flight time.
It is helpful for finding Floating Islands by hovering up and down at the right altitude.
Gravitation effectively surpasses the combination of Rocket Boots and wings as the air travel method with the most range, though it is more difficult to control as a flight method.
It can be used during the Wall of Flesh fight to walk on the roof of the Underworld, avoiding the lava pools, abandoned houses, elevation changes, and Lava Slimes in Expert Mode.
Walking effects, such as the snowy effect when wearing a full set of Frost armor, will not be flipped.
