Although never required in No Glitches Logic, sometimes learning dark rooms will be the difference between single or double dipping a dungeon. In cases where you are racing the seed, this can give you an edge over your opponent. Here's a few maps of dark rooms you may come across that can lead to items in the game. In order to help everyone who is newer to the game, I have edited a couple of maps I had found for use on Ian-Albert.com in order to better assist everyone with finding every possible item location.
While traversing through dark rooms it is recommended to hold out your sword to get the twinkle in order to show your position in the room.

Although the Dark Maze Room looks overwhelming, it actually has a fairly easy pattern to it. Make sure for the top part of the maze, once you move up a bit, you continuously hold left until you are close to the chest (if you hold left all the way to the chest you will need to move right a bit to open the chest). Going to the bottom chest is a bit more challenging but practice a little bit and you can do it!

Turtle Rock Dark Room
