Resurrection Potion

A Resurrection Potion (lit. 复活药水) is a consumable potion which, if in the player's backpack, is immediately consumed upon death, reviving them to full health. They were sold by the Star Merchant as singles, or in packs of three or nine.

Trivia

 * Having a large number of Resurrection Potions on hand can allow a player to easily enter and explore the Dungeon before defeating Skeletron, as the Dungeon Guardians deplete a supply of potions somewhat slowly.
