Without any context, the Red Potion inTerrariamay seem like some sort of challenge-only item that only hinders the player. Such items are not uncommon in the more difficult of games these days (like the Calamity Ring fromDark Soulstrilogy), however, there are sometimes more to them than meets the eye.

The Red Potion was first introduced intoTerrariain order to test how debuffs work on players, which explains its extremely debilitating effects. If players consume a Red Potion, they will receive 11 different debuffs for a lengthy period of time (1 hour in Classic Mode, 2 hours in Expert Mode, and 3 hours in Master Mode).

Afterward, however, they were changed a bit for the sake of a seed-related secret. These usually debilitating potions will instead give players 3 mostly random buffs, but only if they are consumed in a “For the Worthy” world.
