The Rage Potion is a buff potion which grants the Rage buff when consumed. The buff increases a player's critical strike chance by 10%. This lasts for 4 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 (). It appears to be the Crimson variant of the Wrath Potion.

This potion can only be crafted in worlds with Crimson due to it requiring the Hemopiranha, although it is possible to make an artificial Crimson biome in a Corruption world by importing either Crimson blocks, Red Solution, or Crimson Seeds.

As of version 1.4.0.1, it is possible to naturally acquire a Rage Potion in a Corruption world by purchasing Crimson Seeds from the Dryad in a Hardmode Graveyard biome, and using the Crimson Seeds to make an artificial Crimson biome to fish in.
