Magic Mirrors

The Magic Mirror is an item found in Chests in the Underground, Underground Jungle, Ocean, and Dungeon. It allows the user to warp back to their spawn with a roughly one second delay at the cost of 20 Mana. The Mirror was created to discourage players from committing suicide as a method to return home; it allows players with low health to return home without the risk of losing their loot. It is useful if a player finds themselves overwhelmed by enemies, and is also a quick means of escaping out of a Chasm in The Corruption. Note that this item is functionally equivalent to "Save and Exit", except that spawned items (e.g. drops) will despawn upon reload, making the inventory cost somewhat problematic.

Trivia

 * The Magic Mirror was the first item to have its Mana cost changed.
 * Teleporting with the Magic Mirror while under the Horrified debuff from the Wall of Flesh will kill you on arrival of your spawn point/bed.
 * The Magic Mirror is a reference to the game Legend of Zelda: A Link to the Past, in which the player uses a magic mirror to return to the light world when in the dark world, or the first room of the dungeon he was in.
 * There is a bug with the magic mirror where if the user activates it and pauses with the inventory, clicking a random item will make the item glitch with a weird effect.
