Eclipse

Eclipse (Lunar) Damage done by your arcane spells increased by 25%. Cancelled when Starfire causes Lunar Energy to reach 0.

Eclipse (Solar) Damage done by your nature spells increased by 25%. Cancelled when Wrath causes Solar Energy to reach 0.

The Eclipse mechanic is available to all Druids who have specced into Balance, and is active while the Druid is in caster or Moonkin forms. Casting File:Spell Nature wrathv2.png [Wrath] or  [Starfire] will move the Eclipse Bar to an extremity, where it will buff the other spell until the pointer is back at zero.

Mechanics

Casting [Wrath] will cause the Druid to gain 13 Lunar Energy; casting [Starfire] will cause the Druid to gain 20 Solar Energy. Casting [Starsurge] will give 15 Lunar or Solar Energy, depending on which eclipse has last procced. The spell will trigger one of two buffs when Lunar Energy or Solar Energy has reached 100. Eclipse (Solar) or Eclipse (Lunar) will stay active until Wrath, Starfire or Starsurge has been cast enough to move the pointer back to zero. A pointer on the Eclipse Bar indicates which direction the next spell will move it. When cast while an Eclipse buff is active, Starsurge will always cause the bar to move toward zero, and it will continue to generate that type of energy until the other Eclipse has procced. If Wrath is cast during a Lunar Eclipse or Starfire is cast during a Solar Eclipse, it will have no effect on the Eclipse Bar either way.

To summarize, the usual rotation is to cast [Starsurge] whenever it is off cooldown and to cast either [Wrath] or [Starfire], depending on which one will give you energy at the moment.

The main use of the mechanic is the damage, but it also resets the cooldown on [Nature's Grace], as well as giving mana with [Euphoria], so in a PvE environment you should constantly be switching from one eclipse to the other.

Remember that a Solar Eclipse also affects [Sunfire], [Insect Swarm], [Hurricane], [Typhoon] and [Wild Mushroom], and a Lunar Eclipse also affects [Moonfire] and [Starfall], so they should be cast if possible during the appropriate eclipse.

Improvements

The [Euphoria] talent causes your Wrath and Starfire to sometimes generate double energy.

The mastery Total Eclipse increases the benefit of eclipse by 12% + 1.5% per extra point of mastery.

Notes

• A useful strategy in some battlegrounds is to stay in either Lunar Eclipse for an increased effect on  [Starfall] and your  [Moonfire] spam, or to stay in Solar Eclipse to buff your  [Insect Swarm] as well as the then-morphed  [Sunfire] spam.
• The Eclipse procced by File:Spell Nature wrathv2.png [Wrath] is called Lunar Eclipse, whereas  [Starfire] procs Solar Eclipse.
