Lantern Night

A Lantern Night is an event that occurs the evening after a boss or invasion is defeated for the first time, with some exceptions. During a Lantern Night, the player will have an increase to their luck stat, and some NPCs may sell special items.

An unknown NPC may sell the Release Lantern during this event.

Ways to start a Lantern Night

 * Defeat any boss for the first time, with the exception of the Mourning Wood, Santank, or Everscream.
 * Defeat any invasion for the first time, with the exception of the Frost Moon or Pumpkin Moon.
 * Killing the Pumpking or Ice Queen for the first time will start a Lantern Night, however.
 * After defeating the Moon Lord, Lantern Nights may happen randomly.

NPC quotes
The Guide may say these two quotes during a Lantern Night:
 * What a beautiful night! With your recent victory, the world seems more at peace, and these lanterns are in celebration of that.
 * Do you see the lanterns? Now that you've saved our world, there are regular celebrations of your victory. Always such a beautiful sight!
 * This second quote may be exclusive to after the Moon Lord is defeated; please confirm.
