Energy

Energy, represented by the blue bar in the user interface, is basically the character's inner strength; referred to as mana or magic power in most other games. It is consumed when using most types of skills.

Energy capacity
All characters have an energy capacity of 20. This doesn't increase from leveling, but can be increased via certain armor pieces, weapon upgrade components or, in the case of Elementalists, increasing the Energy Storage attribute.

Energy regeneration/degeneration
As with Health, the rate at which Energy regenerates (or degenerates) is represented by small arrows or "pips" that appear in the energy bar. Each "pip" indicates 1 point every 3 seconds of energy recovery (arrows pointing to the right) or loss (arrows pointing to the left). The maximum regeneration or degeneration is 10 pips.

Unlike Health, Energy regenerates even while in combat. Players maintain a "natural" energy regeneration of +2, though rangers get another +1 bonus from most of their armor sets, and the four "caster" professions (Necromancer, Mesmer, Elementalist, and Monk) get another +2 bonus. Thus, casters usually have an energy regeneration of +4, Rangers of +3, and Warriors of +2.

Certain enchantments (unique to the Monk profession) require energy degeneration to maintain, often referred to as "upkeep". Certain items combine Energy bonuses at a tradeoff of energy degeneration.
