Night Light is a passive collectible that was added with the Afterbirth DLC for The Binding of Isaac: Rebirth.
- Isaac is given a cone of light that points wherever he turns. The light slows all enemies and their shots.
- Enemies will return to their normal speed when they are out of the light, but their projectiles will be permanently slowed.
- Bosses are unaffected, but their projectiles will still be slowed.
- Removes Curse of Darkness when picked up, but does not prevent future Curses of Darkness.
- This is part of an unofficial set of bedtime items. The others are: Binky, Mr. Dolly, and PJs.
- Doing a quick, circular sweep is a very effective way to slow projectiles, especially when fighting Hush or Mega Satan.
