||
| − | '''Spell power''', prior to [[patch 3.0.2]] known as '''spell damage and healing''', is an [[attribute]] granted by buffs, talents, and equipment that increases the effect of [[spell]]s. For damage spells, the amount of damage caused is increased, and for healing spells, the amount of healing is increased. Many items will increase damage from all [[Magic schools|magical schools]] as well as healing from all schools, while some items will only increase damage done by a particular school, or only increase healing. Each spell gets a fixed bonus that is determined by the spell type, casting time, target and/or way the spell is applied (the [[spell power coefficient]]). Damage-dealing casters especially consider this attribute to be one of the most important attributes to attain. |

||
| + | '''Spell power''' is an [[attribute]] that increases the effect of [[spell]]s. Spell power increases the damage amount of damaging spells and the healing amount of healing spells. |
||
| + | Your bonus damage and bonus healing from spell power do not usually apply directly to a spell. Each spell (or each component of each spell) which causes damage or healing has a [[spell power coefficient]] which determines how much damage or healing the spell does. |
||
| − | Players often refer to this attribute as simply '''+damage''', '''+dmg''', or '''plus damage'''. For effects that target a specific school, it is similarly referred to by that school such as '''+fire'''. In particular, healers commonly refer to items with only a healing bonus as '''+healing'''. |
||
| + | ==Sources of spell power== |
||
| − | Items with spell damage and healing have the following green "Equip:" text on the item, for example: "Equip: Increases spell power by 26." Alternatively, certain [[item suffix]]es can carry spell damage and healing - items with names ending in "of Fiery Wrath" or "of the Invoker" being two examples. These appear as white text on the item with the rest of the attributes. The effect of these items is equivalent to those with the green Equip: text, except they are spell specific. |
||
| + | Spell power is found primarily on trinkets as an on use effect, but can also be increased with potions. |

As of patch 3.0.2, '''spell power''' now affects both types of spells. Nevertheless, there are items which would increase your '''bonus healing''' independently of damage spells. Similarly, there are items which grant bonuses only to certain [[magic schools]] such as [[magic schools#Fire|Fire]] or [[magic schools#Nature|Nature]]. |

Spell power has also been removed from ''[[World of Warcraft: Wrath of the Lich King|Wrath of the Lich King]]'' gear (except weapons and trinkets) and gems, but casters now gain 1 spell power per point of intellect. Spell power on gems was changed to Intellect; for example, +23 spell power became +20 Intellect. |
||
| − | All spell damage and healing gains [[stack]]. The total bonus is determined by adding individual bonuses from all equipped items, all buffs, and any talents. The total amount of spell damage and healing can be tracked on the [[character sheet]], under the ''Spell'' tab. ''Bonus Damage'' shows the total amount that applies to all schools. Mousing over ''Bonus Damage'' will break down the benefit by magical school, which includes items that only effect one school.

||
| − | === Standard spells === |
||
| − | Standard spells are spells that apply all the damage or healing at one time. To determine the plus Healing or Damage benefit for these spells the following formula is used: |
||
| − | |||
| − | (Cast Time of Spell) / 3.5 |
||
| − | |||

||
| − | || 4.5 sec || 128.6% || 1.5- sec || 42.86% |
||
| − | |} |
||
| − | |||
| − | [[Instant]] spells are treated as 1.5 second cast time spells, with a coefficient of 42.86% |
||
| − | |||
| − | Spells with a cast time longer than 7.0 seconds are capped at 200%. The casting time used in the calculation should be the base cast time '''before''' effects from talents or gear are applied. Note that the tooltip in game includes those effects; refer to the article on a particular spell to get the base cast time. |
||
| − | |||
| − | Examples of such spells include: [[Healing Touch]] (Druid), [[Greater Heal]] (Priest), [[Shadow Bolt]] (Warlock) |
||
| − | |||
| − | Some exceptions of this rule are: |
||
| − | *[[Soul Fire]] (Warlock) - 115% |
||
| − | *[[Pyroblast]] direct damage: 115%, damage over time: 20% |
||
| − | |||
| − | === Over-time spells === |
||
| − | Over Time spells apply healing or damage over a period of time in [[tick]]s. |

||
| − | |||
| − | Prior to [[patch 2.0.1]], there was a 100% cap on over-time spells longer than 15 seconds. This cap has since been removed. |
||
| − | The total bonus is divided equally to each tick. |
||
| − | |||
| − | Examples of these spells include: [[Rejuvenation]] (Druid), [[Renew]] (Priest) |
||
| − | |||
| − | Some exceptions to this rule are: |
||
| − | *[[Shadow Word: Pain]] (Priest) - 110%, increased beyond 140% with [[Improved Shadow Word: Pain]], which extends its duration to 24 sec. |
||
| − | *[[Corruption (spell)|Corruption]] (Warlock) - 93%, can be increased to 129% with the talent [[Empowered Corruption]]. |
||
| − | *[[Curse of Agony]] (Warlock) - 120%. |
||
| − | *[[Curse of Doom]] (Warlock) - 200%. |
||
| − | |||
| − | === Hybrid spells (Combined standard and over-time spells) === |
||
| − | <div id="Hybrid"></div> |
||
| − | The bonus for spells that have both a standard and an over time component is divided between them. |
||
| − | The over time portion receives the following bonus: |
||
| − | |||
| − | (Duration / 15) / ((Duration / 15) + (Cast Time of Spell / 3.5)) = Portion to Over Time |
||
| − | |||
| − | The standard portion receives the rest: |
||
| − | |||
| − | 1 - Portion to Over Time = Portion to Standard |
||
| − | |||
| − | The duration and cast time limits are then applied: |
||
| − | |||
| − | (Cast Time of Spell / 3.5) * Portion to Standard = Total bonus to Standard Portion |
||
| − | |||
| − | (Duration / 15) * Portion to Over Time = Total Bonus to Over Time Portion |
||
| − | |||
| − | Examples of these spells include: [[Moonfire]] (Druid), [[Immolate]] (Warlock) |
||
| − | |||
| − | Exceptions to this rule include |
||
| − | * [[Holy Fire]] (Priest) - 57.5% ([[Direct Damage|DD]]), 18.5% ([[Damage over Time|DoT]]) (As of patch 3.0) |
||
| − | * [[Regrowth]] (Druid) - ~30% ([[Direct Heal|DH]]), 70% ([[Heal over Time|HoT]]) |
||
| − | |||
| − | === Channeled spells === |
||
| − | Channeled spells have their benefit distributed evenly over the time the spell is being cast, getting 100% benefit for the whole spell (not per [[tick]]). The duration of the spell cast time is used as with a standard spell to calculate the total benefit, then divided equally between the number of ticks. |
||
| − | |||
| − | Cast Time of Spell / 3.5 = Benefit |
||
| − | |||
| − | Examples of these spells include: [[Hurricane]] (Druid), [[Arcane Missiles]] (Mage), [[Hellfire]] (Warlock). |
||
| − | An exception to this rule is: |
||
| − | *[[Drain Soul]] (Warlock) - 214.3%. |
||
| − | |||
| − | === Area of effect spells=== |
||
| − | Area of Effect spells receive only 1/2 of the total bonus. The cast time is used as with a standard spell to calculate the total benefit, then divided by 2. |
||
| − | |||
| − | (Cast Time of Spell / 3.5) / 2 = Benefit |
||
| − | |||
| − | {| class="darktable" style="text-align:center;" |

||
| − | |||
| − | Note that some spells fall under the rules for multiple spell types. Hurricane, Tranquility and Hellfire, for example, are all Area of Effect and Channeled. Prayer of Healing is both a Standard Spell as well as an Area of Effect spell. |
||
| − | |||
| − | In the [[Burning Crusade]] and patch 2.0 there is a diminishing return against multiple targets. That is, as the number of targets your spells affect increases, the less damage you will deal to them. The numbers for this mechanic aren't yet known. |
||
| − | |||
| − | === Paladin special attacks === |
||
| − | |||
| − | Some Paladin abilities work different ways. Here are some formulas tested in [[beta]] version of the [[Burning Crusade]]. |
||
| − | |||
| − | [[Holy Shield]], [[Retribution Aura]] (Paladin) reflects damage: |
||
| − | |||
| − | 5% of +spell damage effect = +damage applied for each charge |
||
| − | |||
| − | Only Paladin aura benefit from +dmg. A Druid's Thorns spell doesn't get its damage increased except by the Brambles talent. |
||
| − | |||
| − | [[Seal of Righteousness]], which applies holy damage on each melee attack: |
||
| − | |||
| − | [[One-handed]] [[weapons]]: |
||
| − | |||
| − | 9.2% * [[Weapon Speed]] in seconds = Total |
||
| − | |||
| − | 1.0 sec = 9.2% |
||
| − | 2.2 sec = 20% |
||
| − | |||
| − | [[Two-handed]] weapons: |
||
| − | |||
| − | 10.8% * [[Weapon Speed]] in seconds = Total |
||
| − | |||
| − | 2.6 sec = 28% |
||
| − | 3.7 sec = 40% |
||
| − | |||
| − | == Rules for applying spell damage and healing == |
||
| − | #Calculate spell time using the base spell cast time '''before''' talents and gear. (The in-game tool tip will include those bonuses; refer to WoWWiki's [[spells]] section for base cast times for all spells.) |
||
| − | #Spells that take longer than 7.0 seconds to cast are treated as if their casting time was 7.0 seconds, and spells faster than 1.5 sec are treated as if their casting time was 1.5 seconds. |
||
| − | #Damage benefits are applied before any talents or buffs that may otherwise increase your spell damage. |
||
| − | |||
| − | == Penalty rules == |
||
| − | === Spells learned before level 20 === |
||
| − | Many spells have multiple ranks. To avoid abuse of lower ranks to have a similar effect at a negligible mana cost, any spell learned below level 20 receives a large penalty. If such a spell has a shorter cast time than a higher rank, this is also taken in to account. This penalty can be calculated by subtracting 3.75% for each level lower than 20. |
||
| − | |||
| − | (20 - Level Spell is Learned) * .0375 = Penalty |
||
| − | |||
| − | === Downranked spells === |
||
| − | {{main|Downranking}} |
||
| − | |||
| − | Downranking, the act of purposefuly using a lower-rank cheaper spell, is no longer possible as of patch 3.0. |
||
| − | |||
| − | . |
||
| − | |||
| − | === Spells with additional effects === |
||
| − | Spells with additional effects, like a slowing effect, get a 5% penalty to damage and healing bonuses. This penalty is applied after the spell type calculation, before other penalties. For example, a standard area of effect spell with an slow effect would be calculated like so: |
||
| − | |||
| − | ((Cast Time of Spell / 3.5 ) * .95 Penalty for extra effect) / 3 = Benefit |
||
| − | |||
| − | Examples of these spells include: |
||
| − | [[Blast Wave]] (Mage), [[Blizzard]] (Mage) |
||
| − | |||
| − | The above calculations are for Area of Effect spells with a snare, identified by the " / 3" at the end. For single-target spells, use the following formula: |
||
| − | |||
| − | ((Cast Time of Spell / 3.5 ) * .95 Penalty for extra effect)= Benefit |
||
| − | |||
| − | Examples of these spells include: |
||
| − | [[Entangling Roots]] (Druid), [[Frostbolt]] (Mage) |
||
| − | |||
| − | Note that in patch 2.1, multiplier for additional effect has changed a lot. For some spells the multiplier is still 0.95, while it might be quite different in many other cases. |

| − | === Spells that both damage and heal === |
||
| − | Some spells, namely [[Drain#Life_Drains|Life Drains]], both damage the target and heal the caster. These spells have a 50% penalty to the bonus they receive, but bonuses to spell damage increase both the damage and the healing of the spell equally.

- "Spell Power" redirects here. For the former mage talent, see
[Spell Power]. - "Spellpower" redirects here. For other uses, see Spellpower (disambiguation).
Spell power is an attribute that increases the effect of spells. Spell power increases the damage amount of damaging spells and the healing amount of healing spells.
Your bonus damage and bonus healing from spell power do not usually apply directly to a spell. Each spell (or each component of each spell) which causes damage or healing has a spell power coefficient which determines how much damage or healing the spell does.
Sources of spell power
Spell power is found primarily on trinkets as an on use effect, but can also be increased with potions.
Additional notes
- Spell power does not apply to bandages or potions.
History
Prior to patch 3.0.2, the attribute known as spell damage would only increase the effects of damaging spells. Healing spells were only increased by the healing attribute. As of patch 3.0.2, spell power now affects both types of spells. Nevertheless, there are items which would increase your bonus healing independently of damage spells. Similarly, there are items which grant bonuses only to certain magic schools such as Fire or Nature.
As of patch 4.0.1 the ability to downrank has been removed. Spell power has also been removed from Wrath of the Lich King gear (except weapons and trinkets) and gems, but casters now gain 1 spell power per point of intellect. Spell power on gems was changed to Intellect; for example, +23 spell power became +20 Intellect.
Patch changes
Patch 7.0.3 (2016-07-19):
- Spell power has been removed from caster weapons and their bonus to Intellect greatly increased to compensate. Trinkets using spell power have had their bonus significantly increased.
- Spell power has been removed from the default character sheet.
Patch 4.0.1 (2010-10-12): Spell power has been removed from all armor (except 
[Feathermoon Headdress]). - Patch 3.0.2 (2008-10-14): All items and effects which grant bonuses to spell damage and spell healing are being consolidated into a single stat, Spell Power. This stat will appear with the same values found on items which grant "increased spell damage and healing" such as on typical Mage and Warlock itemization.
- For classes which do not heal, they should see no change in the character sheet other than new tooltip wording.
- Healing characters will see their bonus healing numbers on the character sheet decrease, however, all healing spells have been modified to receive more benefit from Spell Power than they received from bonus healing, with a net effect of no change to the amount healed by their spells. Some talents have had to be rebalanced to accommodate this change, but the amount healed will remain roughly the same. In addition, some talents will provide only healing spell power.
