I’ve been getting more emails lately asking for clarification on what buffs stack with each other, and what buffs do not stack in raids, so it seemed like a good time to clarify exactly how this works. Blizz changed how raid buffs work in WoW so that just about any buff that does the same thing as another buff does not stack with the similar buff. Debuffs work the same way. In all situations, you will get whichever buff helps you the most.
Here is a list of all the raid buffs (and debuffs) that I’m aware of and how the stacking works. You can only get one buff from within each category. Thus if you have Trueshot Aura and a shammy with unleashed rage, they will not stack. You just get one. Also obviously you do not get the benefit from two of the same buff within a category on this list.

Horn of Winter is Death Knight not Shammy just wanted to let you know so you could fix it.
Assassination Rogues can bring the Crit Chance Taken debuff (Master Poisoner) and Combat Rogues bring Physical Vulnerability (Savage Combat).
improved moonkin aura also give the +3% spell haste buff that wrath of air totem does
warlock’s improved shadow bolt also gives the spell crit debuff that mages give.
Speaking of stacking, when another Hunter applies their Serpent Sting to a target, mine is eliminated from my buff/debuff icons. Do we still get the damage modifier(s) with someone else’s sting up, or does it have to be our own?
So… Frost… if say you were looking at a blog somewhere and you noticed an error and/or an ommission, what would you do? what if you were friends with that person? Would you point it out and ridicule them, as per the man code?
Long list! I Prefer MMO-champions feature:
http://raidcomp.mmo-champion.com/
There is no longer improved divine spirit, the talent went away when the spell became core.
What about Blessing of Wisdom?
Neven: if I noticed an error/ommission on some random blog, I wouldn’t do anything. If I was a regular reader, I’d probably politely point out what I thought was the error in a logical way. If I was friends with the blogger, probably the same thing.
The guy code does not say we must ridicule each other for errors. It just says that such ridicule is perfectly acceptable.
Grace no longer gives the -3% damage buff; that’s Renewed Hope, and in testing it has been seen that Renewed Hope and Blessing of Sanctuary stack multiplicatively.
what about wolf ability Furious Howl , does it stack with BoM or not ?
Under hunter’s mark it says only hunters benefit. Tool tip for this skill would indicate otherwise.
I spent all morning arguing with a friend about this; Call of the Wild increases pet & hunters melee & ranged attack power by 10%. Does this stack with something like Trueshot aura?
What about food buffs? If I’m hit capped, should i eat the fish feast that is thrown down every 20 min, or something else like Blackened Dragonfin?
[url=http://www.wowhead.com/?spell=3738]Wrath of Air Totem[/url] and [url=http://www.wowhead.com/?spell=48396]Improved Moonkin Form[/url] DO stack.
I’m no expert, especially not on raid buffs, but don’t mages also have Arcane Empowerment, which stacks with Ferocious Inspiration?
Why is focus magic in the increased spell power group?
Irmie – What other class uses ranged physical attacks? Warriors shooting? Rogues throwing?
Focus Magic is a unique buff independent of all others and increases the spell critical strike chance of the target by 3%. Also, when the target critically hits it increases the caster’s chance to critically hit with spells by 3%.
Arcane Empowerment is exclusive of Ferocious Inspiration and Sanctified Retribution.
Wrath of Air Totem and Improved Moonkin Form are also exclusive and DO stack.
Improved moonkin aura does not give spell haste, it gives haste, which only doesn’t stack with the ret pally aura buff ie, it does stack with wrath of air totem.
Can anyone Confirm whether or not, Kings 10% stacks with TSA I know that my AP changes if I use Drums Kings 8%.. but I dont see a change with 10%
Would love to get this list updated
Increased Spell Power Buff
Focus Magic (mage)
Flametongue Totem (shammy)
Totem of Wrath (shammy)
Demonic Pact (warlock)
Focus Magic (mage) should not be in this list as it does not give spellpower buff. It increases crit 3% and when that target crits the mage gains 3% crit.
Focus Magic does not increase spell power, it increases a single target’s spell critical strike rating.
Um for spirt buffs pally’s BoW fits in there dosent stack with priest PoS ect ^.^
you missing rogue debuff from list
Critical Strike Chance Taken Debuff (All types 3%):
Heart of the Crusader – Ret Paladin talent
Totem of Wrath – Elemental Shaman talent
Master Poisoner – Assassination rogue talent
I was running randoms last night and I noticed my trueshot aura kept disappearing. We did not have a shammy or a DK in our group. The only person getting my buff was the person not getting the blessing of might. Does trueshot no longer stack with might or was I glitching?
“Does trueshot no longer stack with might or was I glitching?”
Today, at my raid, i saw this… They dont stack or is a bug?
how many time i do not do what i want to do but do what i dont want to do
