Spell power coefficient
From Wowpedia
(Redirected from Spell power coefficients)
Spell power coefficient is an intrinsic property of a spell that determines how much bonus damage or healing it gets from the spell power attribute accumulated from gear, buffs, and talents. In most cases, the coefficient is fixed for a spell; in other cases, it is changed by talents, such as various "empowering" talents, available to some caster classes. Spell power coefficients usually follow set rules outlined in the spell power article, but many exceptions exist. Exact spell power coefficients are tested experimentally and documented when well known.
The listed coefficients are base coefficients and apply for the whole spell and per target, unless otherwise stated. In addition, if talents which specifically affect the coefficient exist for a spell, they are mentioned as well. Any effects which increase overall damage and/or healing, be it directly (e.g. 
[Moonfury]) or indirectly, are not listed here.

Notes
- ^ Without
[Wild Hunt] - ^ Ignores Spellpower from Spirit (Fel Armor and Life Tap Buff)
- ^ Voidwalker appears to recieve a 40% increased amount (0.57 * 1.4) of attackpower from the master, maybe needs some further testing
- ^ A single casting of Gift of the Naaru does not receive bonus healing from both attack power and spell power, instead, each casting uses the higher of the two bonuses.
