Red Potion

The Red Potion is a debuff potion that inflicts the Darkness, Poisoned, Cursed, On Fire!, Weak, Confused, Slow, Silenced, Broken Armor, Bleeding, and Suffocation debuffs on the player that consumed it for 1 hour /, effectively killing the player.

Trivia

 * This is a testing item that was changed before the release of the 1.2.2 update to test giving ordinary players debuffs instead of buffs.
 * Tipsy is an example of a current obtainable debuff that can be inflicted by consuming potions, which most likely exists thanks to this test.
 * It replaced the Soul Scythe in the game's code when it was introduced.
 * There is an 'R' on the potion's lid, most likely a reference to its name.
 * It is the only non-flask potion to have a gold top. Flask of Gold does have a gold top, if you include flasks.
 * It is possibly the terraria equivalent of Minecraft's notch apple, as both are named after the lead developer of their respective games.
