Rage Potion

The Rage Potion is a buff potion which buffs the player with Rage. The buff increases a player's critical strike chance by 10%. This lasts for 4 minutes, but can be cancelled at any time by right-clicking the icon.

The Hemopiranha, a crafting material required for this potion, can only be found in ponds near Crimson blocks. This means that the Rage Potion is naturally unobtainable in Corruption worlds. It appears to be the Crimson variant of the Wrath Potion.
