Scrolls Of Different Ranks Stack Together

[yasuno]

For instance, if you get all the different types of scroll of agility its the same spell except different ranks basically. Except you can stack all of them so you can run around with about 12 agility buff auras on you.. This is extremely unfair lol.

100 % confirmed, very bad bug, all instance now very easy

100 % confirmed, very bad bug, all instance now very easy

I can also confirm, but disagree that all instances are very easy

[Betaman2k]

ehmm all bosses make spells = the player pushed up with residentl ( 300 + ), now PvE and PvP very bad

[darkstalker]

lots of stuff stack, like different totems ranks and magic resistance buffs (should take only highest rank)

[Betaman2k]

yes sir confirmed, major bug

[laise]

are you sure you have right values in spell_chain ?

[Betaman2k]

i checked the tabs

spell_id

prev_spell

first_spell

rank

req_spell

i saw no error, what do u mean

[dardennf]

I think there is no spell_chain between this spell : Gift of the wild and this one : Mark of the wild, but you shouldn't stack them.

Another exemple : Fire resistance totem and Fire resistance aura should not be stackable.

On retail you can only have the spell which add the biggest amount of a same stat or at least if they grant the same value, one of them which is replaced by the new one.

Last example with stamina buffs : currently you can stack all these followings buffs Power Word : Fortitude and Fortitude and Scroll of stamina it's quite a big deal because you have about 300 more stamina that you can normally have.

Sorry for my english.

it still not completed patch, but it already prevents from stacking bonuses http://paste2.org/p/1067043 . Author is me, dbc part by nos4r2zod

TODO:

Reapply old bonus in case strongest aura is removed but the weak aura still exist. It would be good If someone help me to complete this patch

[darkstalker]

so SPELL_ATTR_EX7_UNK28 related to buff stacking?

about the patch.. don't think that modifying each aura basepoints is a good idea, could cause asymmetric apply/remove, and aura value is lost in the process. Maybe better to calculate max value at apply/remove modifier.

Personally i think everything that adds a distinct buff icon should stack.. this is one of those stupid restrictions that blizz adds to the game.

Recently I've been trying some things in aura update to prevent stacking (mostly area auras from talents and totems).

Imho there are two ways of dealing with it. In abstract: in every aura update check if there are other buffs of this type, and if there are weaker ones then somehow freeze them (icon should be seen but have no effect) or do this when an aura applies/fades (more optimal I think).

Am I to understand you that if you buff

30IntScroll, 20IntScroll, that then only the 30IntScroll will have an effect, but when the 30IntScroll aura expires, the effect of the 20IntScroll will become active?

I think for now we all would be happy if

bool SpellMgr::IsNoStackSpellDueToSpell

would return better results

I believe it is way it should work. You can read blue post about buff stacking http://www.wowwiki.com/Buff#Buffs.2C_debuffs.2C_and_raid_stacking_in_WotLK

[darkstalker]

for scroll case yes, but there are tons of auras that should stack visually, but the net effect should be only the maximum value of the category, example: resistance buffs

No, this does not work like this.

If you buff yourself/anyone with 30 Int Scroll, then the attempt to buff the same target with 20 int scroll will result in an error message like "There is a better buff already".

For aura, only the highest is applied. If the owner is no more in range or no more alive, the next one applies (totem, paladin aura...)

For buffs with same level or higher than previous applied one, the last and higher one is applied and the other is canceled forever.

There is no error when applying a raid buff weaker than an existing one (it's just ignored) while you have a clear message if you try to single buff someone which already has a higher buff.

Only the non-stacking effects should be handled, right?

For example, effect 3 of Vigilance shouldn't stack with effect 1 of Sanctuary.

The other effects, 2 from Vigilance and 2 from Sanctuary, must be applied though.

edit: someone really needs to run a WotLK-only site... all of these spells are changing!

[darkstalker]

i got my personal dbc browser, but still on early development

[Revils]

For aura, only the highest is applied. If the owner is no more in range or no more alive, the next one applies (totem, paladin aura...)

For buffs with same level or higher than previous applied one, the last and higher one is applied and the other is canceled forever.

How sp/haste buffs from procs from different trinkets or with wrath totem or demonic aura are handled?

[faramir118]

Only certain spells are included in nonstacking categories of buffs/debuffs. The challenge is identifying which spells are in which categories (and then applying only the greatest buff/debuff in that category).

Spells that aren't in a category stack like normal.

See raidcomp tool.

[Neo2003]

Of course procs stack.

They don't stack only in case they are both same, like when you have berserker on 2 one hand weapon. If the second proc when the one did already, as far as I remember, the 2nd proc is ignored. Having 2 times the same proc just optimizes the uptime as long as they don't proc in the same period.

And for "on activation" item buffs, bliz clearly states on the item with what it does not stack: "... is sharing its cooldown with...." type of text.

Note: I talk about 3.3.x ofc.
