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 innate energy capacity of 20. This doesn't increase from leveling, but can be increased via certain armor pieces, weapons, weapon upgrades or, in the case of Elementalists, increasing the Energy Storage attribute. All standard Warrior armor provides no modifier to maximum energy (with the exception of Gladiator's Armor), while all Ranger armor sets provide +5 maximum energy, (with the exception of Druid's Armor, which provides +12). Most sets of spellcaster armor provide +10 maximum energy (with the exception of Ascetic's Armor, Enchanter's Armor and Scar Pattern Armor, each providing +17 energy).

A special case is when some Elementalist spells give the caster exhaustion, which temporarily lowers the maximum amount of the player's energy.

Any temporary effects on energy capacity also modify current energy by the same amount, albeit also temporarily. For example, if a character with 15 of 40 energy has his maximum energy reduced by 12 (perhaps by unequipping a focus), he would then have 3 of 28 energy. It is possible to reduce current energy below zero in this manner. In such a case, the UI will indicate the character has zero energy until his energy is once again greater than zero (cause by any means, whether by equipping an item, natural energy regeneration, or other sources of energy).

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 and players have a natural regen of +2 pips that does not increase naturally. As with Energy capacity, Energy regeneration can be increased via certain armor pieces. Warrior armor sets provide no extra Energy regeneration, Ranger sets provide a +1 bonus, and all other professions (Necromancer, Mesmer, Elementalist, Monk, Ritualist, and Assassin) get a +2 bonus from their armor. Thus, warriors have an energy regeneration of +2, Rangers of +3, and all other professions +4.

Some Monk and Assassin enchantments require energy degeneration to maintain, often referred to as "upkeep". Some items combine Energy bonuses at the cost of energy degeneration.
