Power Word: Shield (abbr. PW:S) is a defensive priest Power Word available at level 6. It creates a protective shield around a friendly target which absorbs a set amount of damage. Power Word: Shield also gives the target the Weakened Soul debuff, preventing the target from being shielded again for 15 seconds.

While Power Word: Shield is a valuable spell for any priest, Discipline priests have the opportunity to improve it far beyond its base effect, using it to restore mana, grant haste and even reflect damage back upon the attacker. Power Word: Shield is undoubtedly one of the signature spells of the Discipline priest, protecting the target with a powerful shield that can seem unbreakable.

Notes

  • Has a spell power coefficient of 87%.
  • Absorb effects apply after damage reduction effects, including armor. If the damage of an attack is partially resisted or reduced by another effect, this will lower the amount of damage remaining to be absorbed and allow a shield to last longer.
  • The Discipline mastery Spell holy divineprotection [Shield Discipline] increases the amount absorbed by shield spells such as Power Word: Shield by 20%, with an extra 2.5% added for each point of mastery.
  • Power Word: Shield absorbs damage only. Most other effects attached to a damaging attack, such as a debuff that the attack applies or a spell interrupt will ignore the shield even if the attack deals no damage. Exceptions are Spell frost stun [Dazed] effects from being attacked from behind and spell pushback, which are both prevented.
  • Environmental damage (fall, fatigue, drowning) is not absorbed.
  • Generates about half the threat of normal healing spells.
  • The shield cannot absorb health paid to pay the cost of an ability such a Spell shadow burningspirit [Life Tap] or Spell deathknight bloodtap [Blood Tap]. Such health lost ignores the shield.
  • Warriors and druids are still able to generate rage from damage absorbed while shielded.
  • Power Word: Shield costs the same as 2 x Spell holy renew [Renew].

Items

Tips and tactics

  • Casting it before combat does not cause any threat and reduces the time until the target can be shielded again.
  • A major disadvantage of the shield is that it is a limited form of damage mitigation, not a true healing spell, and so may wear off without having been of any use. With a limited duration of 15 seconds, priests must choose their timing in order to ensure mana is not wasted casting the spell to little or no advantage.
  • Mana efficiency of Power Word: Shield is typically predicated upon the shield being fully absorbed. In practice, with only a 15 second window for this to occur, in many situations the shield will fade without being completely absorbed. In these cases the spell can be considered to be far less mana efficient.
  • Power Word: Shield upon enemy targets can be dispelled with Spell nature nullifydisease [Dispel Magic], Spell arcane massdispel [Mass Dispel] and similar spells.
  • Paladins want to be healed rather than shielded, even though they are perfectly capable of using Inv glove plate raidpaladinmythic q 01 [Divine Plea] and Ability paladin judgementblue [Judgement of Wisdom]. They receive mana from heals, but not from Power Word: Shield. Paladin tanks have tiny mana pools and rely on healing or will go oom.
  • The effectiveness of Power Word: Shield is not altered by Ability warrior savageblow [Mortal Strike] and similar healing-reducing debuffs; in these situations it can sometimes be more effective to shield a tank first, rather than spam heals right away.
  • This is useful for casters who are receiving damage, as it prevents spell interruption from damage, especially while they are channeling, and even the priest himself can benefit from this (especially in solo combat).
  • In PvP, this spell can be a huge boon to bestow on Rogues and Feral Druids. Any damage taken will unstealth a character. However, if you Power Word: Shield a Rogue, AoE damage that doesn't get through the shield is absorbed, which greatly increases the difficulty of finding a Rogue by laying down an AoE. Power Word: Shield will also absorb the damage from DoT's, allowing DoT'd Rogues to Vanish safely. Just know that if the AoE or DoT damage is greater than the shield will take, then the actual character will take damage and stealth will become undone.
  • Power Word: Shield can also be seen as a way of pushing a tank's health beyond its normal limit. It is effective to Power Word: Shield before major attacks that will destroy the shield in one blow. Using it before Patchwerk's Hateful Strike or similar devastating attacks reduces the chance that a tank will die to a possible critical hit after such an attack.
  • When glyphed with Inv glyph majorpriest [Glyph of Power Word: Shield], priests may wish to allow targets to take a small amount of damage before shielding them, in order to benefit from the additional 20% direct heal.
  • There was a time when Power Word: Shield would only be used in case of emergency because of its large mana cost and cooldown. Now it is a mainstay of healing for priests and is actually one of their most mana efficient heals.
  • The Weakened Soul debuff can be shortened to 13 seconds with the 4 piece bonus from Gladiator's Investiture.

Bugs

  • The bonus given by Spell holy sealofvengeance [Twin Disciplines] do not apply correctly to the amount absorbed by the shield; the bonuses are added instead of multiplied. Thus, when fully talented, the size of the shield is multiplied by 1.09 rather than 1.092. (4% & 5% = 1.04*1.05 = 1.092)
  • Inv glyph majorpriest [Glyph of Power Word: Shield] does not take into account the bonus from Spell holy powerwordshield [Improved Power Word: Shield] when calculating the healing amount.
  • The amount healed by Inv glyph majorpriest [Glyph of Power Word: Shield] is increased by any talents or effects the target has that increase healing done. For example, if the effect is used on a Restoration Shaman, the heal will be increased by 10% because of Spell holy dispelmagic [Purification].

Formula

Formula for calculating Power Word: Shield's total absorption amount, as of Patch 4.1:

(8136 + (0.87 * SP) * SD * SH * IMP * TD)

Example: a rather modest Discipline priest with 3600 Spell Power, 5 points of Mastery and with both Spell holy powerwordshield [Improved Power Word: Shield] and Spell holy sealofvengeance [Twin Disciplines] fully talented.

(8136 + (0.87 * 3600) * 1.325 * 1 * 1.2 * 1.06) = 18991

It should be noted here that PW:S absorb effects apply after damage reduction effects. This means that while the amount absorbed here is 18991 the character will most likely take far more than 18991 damage before the shield is completely absorbed.
