Let’s start with the basics. A revenant can select from a pool of legends—epic characters from the past that you can invoke power from—and slot two different legends at a time. With this constant connection to the Mists, you’ll always have one active legend and one inactive legend. The current active legend will determine the skills on the right half of your skill bar. It’s similar to weapon swapping, but instead it affects your healing, utility, and elite skills. Not only will the legend you select determine your skills, but you’ll have an energy bar tied to your currently invoked legend.
This energy bar is a new resource that the revenant relies on in order to use skills. Some skills will have a low energy cost, allowing you to use them more often, while others have a large cost with a very large payoff. When you invoke a new legend, you’ll begin at half energy and generate more energy over time. This creates a push-and-pull feel with the energy that you manage as you use your skills.
Revenants also have upkeep skills, which you may remember from the original Guild Wars. Certain legends have skills available that will cause you to lose the ability to regenerate energy or even put you into a degeneration state while they remain active. These skills will last until you run out of energy or toggle them off. As you can see in the screenshot, there are pips that represent your current state of upkeep. This allows us to have another skill type in Guild Wars 2 with unique functionality and reinforce the revenant’s focus on energy management.
