Spell Power

From Heroes of the Storm Wiki
Jump to: navigation, search

Spell Power (also Ability power) Modification increases or decreases the Spell Damage, Healing and Shields done by a Hero's Abilities. Summoned creatures (Zagara Roaches, Azmodan Demons, etc.) deal ability damage which can be enhanced by the Hero’s Spell Power in real-time.

A Spell Power value greater than 0% effectively increases the damage dealt or healing provided by the same percentage (ex: An ability that deals 100 damage would deal 140 damage with 40% spell power, 100+100*40% = 140). Similarly, a Spell Power value less than 0% effectively decreases the damage dealt or healing provided by that percentage (ex: An ability that deals 100 damage would deal 60 damage with -40% spell power, 100+100*-40% = 60). Damage modified by Spell Power is calculated the moment the target is hit.

Spell Power modification is calculated after Scaling and flat damage bonuses from Talents.

Spell Power does not affect Healing gained through Lifesteal, though can alter lifesteal amount based on spell damage by altering this damage.
