"Energy management" refers to any method used by a character to actively recoup energy faster than normal or, in general, a plan for utilizing energy in an efficient manner. This article is a brief overview of energy management techniques often used in the Player-versus-Environment (PvE) aspect of the game. In addition to what skills are used, a character's overall build in terms of skill cost, cooldown (i.e. how often a skill can be used), attributes (e.g. Expertise and Soul Reaping), and equipment (e.g. zealous weapon upgrades) are important considerations for energy management.
