Exhaustion reduces the character's maximum energy by 10 points for each spell cast under exhausting circumstances; the maximum can drop below zero. Maximum energy recovers at a rate of 1 point every 3 seconds (in other words, it takes 30 seconds to fully recover from one exhaustion-causing spell).
The reduction of the maximum displays as a grayed-out fraction of the energy bar, as shown in the example.
Elementalists can exhaust themselves as they begin casting certain spells; if interrupted or canceled, these skills will still cause exhaustion:
- Energy Storage: Ether Prodigy
- Air Magic: Gale, Mind Shock, Ride the Lightning, Shock
- Earth Magic: Dragon's Stomp, Earthquake, Obsidian Flame
- Fire Magic: Meteor, Meteor Shower, Mind Burn
- Water Magic: Maelstrom, Mind Freeze
- No Attribute: Second Wind
Two spells only cause exhaustion at the end of casting, and then only if the caster is not enchanted:
The following skills also cause exhaustion:
- Equinox causes a second exhaustion at the end of casting;
- Exhausting Assault exhausts the target if it interrupts a spell;
- Arcane Languor causes hexed foes to exhaust themselves whenever they cast spells;
- Crystal Haze (Monster Skill) causes hexed foes to exhaust themselves when using any energy-based skill.
The following environment effects cause exhaustion:
- Aspect of Exhaustion inflicts exhaustion every 30 seconds.
- Sheer Exhaustion causes all spells to inflict exhaustion.
The only way to remove exhaustion is by waiting or changing zones; there are no skills to remove it.
- Glyph of Energy prevents your next spell cast from causing exhaustion.
- Exhaustion's effect on the energy bar displays similarly to Deep Wound's impact on the health bar.
