I'm not sure if a map of the Rift was made before, but I made one a while ago. If you don't want to use it, then don't. If you do, then it's right here~! I've been seeing so many people get lost xD
That map only shows the correct routes, so you're going to have to figure out which turns to skip or use based on it.

Edit: Feel free to expand on it with all the other wrong routes, btw, so it's a full map. I'm not dealing with it, I had to continuously take screenshots and match it to the drawing... it took hours. ^^;
