           Actually there really isn't anything in Crypt of Decay that you can be confused as to the use. The only thing that I saw that could confuse some players is the Ethereal and Spectral Parchments. To learn more about these parchments click here. (Link to my guide in the future)

Level 55 to 60
If you're solo then there really is no place safer then the zone line. Stay by it and pull puslings to it until around level 60. It may be hard to find a group in this zone, due to its size it doesn't support that many people. Even just staying at the zoneline you'll usually breeze through these levels.

Level 60 to 65
Once again assuming you're solo and probably have a merc it's best to head to the Rats or stick with the zoneline. The rats are at the northern portion of the zone, if you scroll out to see the whole map you'll notice a huge tunnel system to the north, this is where the rats are. They will take you to level 65 quickly, after that they turn LB and the xp drops dramatically.

Level 60 to 65 (Alternate Route)
Along with the rats there is also another camp in the zone to the west, the undead camp. They are very similar to the rats in level and amount of money you can make off the drops. Although this camp is inferior in one major way, It has a raid boss nammed Carprin Deatharn that can spawn right in the center of it.

Level 65 to 70 (Not Recommended)
If you stay in this zone till level 70 you're going to experience the "HELL" of hell levels. You can grind out these levels here in the undead or rats, but I HIGHLY do not recommend it.

This zone is included in my farming guide, which can be viewed here.
