Luna

Luna is a passive item added in The Binding of Isaac: Repentance.

Effects

 * Adds an extra Secret Room and Super Secret Room to each floor.
 * Reveals one random secret room on the map on pickup and at the start of each floor.
 * Each newly discovered Secret Room has a shining beam of light that will raise tears for the current floor and gives Isaac half a soul heart when walked under.
 * The first light gives Isaac +1 tears fired per second, and all subsequent ones give +0.5 tears fired per second.
 * This gives a potential +2.5 tears per second for a given floor, on top of 2 soul hearts.
 * The tears up breaks the default 5 tears per second cap.
 * Once the effect is triggered for the floor, a silver-bluish shine will appear around Isaac. This light will be strengthened for every beam of light "gathered".
 * While this effect is mostly cosmetic, it also partially counteracts both the Curse of Darkness and the "dark rooms" in the /.

Interactions

 * Fragmented Card: The effects stack, spawning three secret rooms on the floor. All three secret rooms will contain beams of light.

Trivia

 * Luna is the Latin word for moon, and is currently used in some Latin-based languages with the same meaning.
