There are six sizes of raids: Personal, Small, Medium, Large, Epic, and Colossal.
Each raid, regardless of size (exceptions Titanic Raids, Personal Raids), has one of four difficulties: Normal, Hard, Legendary, Nightmare and uses either one of the three types of power: Energy, Honor, and Stamina, again with the exception of World Raids and Event Raids which use all three.
When looking at a raid on your raid page, the name of the raid will be in the top left corner, and the name will be a color that will tell you what the difficulty is.
The colors are Normal = Green, Hard = Yellow, Legendary = Red, Nightmare = Purple.
- To add a raid to these lists just add the relevant category to the raid's page. (except for Raids by Zone)
