Holy Shock

Holy Shock is a Holy-based spell for the Paladin. Depending on your target, it does either direct damage or healing. It is an active ability gained by Paladins who choose to specialize in the Holy Tree, and is not available to Protection or Retribution Paladins, or to any paladin before level 10.

Rank table
Holy Shock is obtained as soon as you specialize in the Holy Tree, which can be done as early as level 10. Starting with patch 4.0.1, all spells automatically scale with character level, becoming more powerful each time a character gains a new level. The following table lists the base power of Holy Shock at various levels, including points at which the spell becomes significantly more powerful:

Talent Improvements

 * Blazing Light: Increases the damage of your Holy Shock and Exorcism by 10/20%.
 * Conviction: Gives you a 1/2/3% bonus to damage and healing for 15 sec after causing a critical effect from a weapon swing, spell, or ability. This effect stacks up to 3 times.
 * Crusade: Increases the damage of your Crusader Strike, Hammer of the Righteous and Templar's Verdict by 10/20/30% and the damage and healing of your Holy Shock by 10/20/30%.
 * Daybreak: Your Flash of Light, Holy Light and Divine Light have a 10/20% chance to make your next Holy Shock not trigger a cooldown if used within 12 sec.
 * Divinity: Increases all healing done to and by you by 2/4/6%
 * Infusion of Light: Increases the critical effect chance of your Holy Shock by 5/10%. In addition, your Holy Shock critical effects reduce the cast time of your next Holy Light by 0.75/1.50 sec.
 * Protector of the Innocent: Casting a targeted heal on any target, including yourself, also heals you for X.

Tips and Tactics

 * Starting in Patch 4.0.1, Paladins generate holy power which is used to power various abilities. Holy Shock is one of the two primary methods a Holy Paladin uses to generate holy power (the other being Tower of Radiance)
 * Holy Shock the second cheapest healing spell available to the Holy Paladin, and is significantly stronger than Holy Light. With only a 6 second cooldown, it should be used often for both power and efficiency.
 * When you proc Daybreak, your next Holy Shock will cause no cooldown. The talents Infusion of Light and Speed of Light grant you specific benefits following a successful cast of Holy Shock. This allows you to cast multiple spells in rapid succession; for instance, with Daybreak up, you could utilize the reduction in cast time on Holy Light twice in rapid succession, by casting: Holy Shock, Holy Light, Holy Shock, Holy Light.

Origin
In Warcraft III the Paladin hero's Holy Light spell healed friendly living units and damaged enemy undead units. Considering this, some may view Holy Shock as a variation of WC3 Holy Light.
