Red Potion

Red Potion is a buff potion that inflicts the Burning and Suffocation debuffs on the player that consumed it, unless the consuming player is a member of Terraria's development staff.

Trivia

 * It replaced the Soul Scythe in the game's code.
 * This is a testing item that was changed before the release of the 1.2.2 update to give ordinary players debuffs instead of buffs.
 * In most role-playing games, red potions are considered healing potions. Ironically, the Red Potion will harm the player when consumed.
