SPELL_ATTR_EX6_UNK23 = 0x00800000 seems to be "non stacking DEBUFF"

and SPELL_ATTR_EX6_UNK26 = 0x04000000 seems to be "non stacking BUFF"

And there is also something interesting, Sunder Armor aura does not have SPELL_ATTR_EX6_UNK23, BUT Sunder Armor client spell which has effect TriggerSpell (which is the aura) has this flag. So maybe there should be check if the aura or spell which triggered the aura has the flag.

Hello again.

I got back to the research and fixed auras stacking system, basing on work of nos4r2zod.

Patch for revision 11453

http://pastebin.com/PGu6FkTQ

Authors: nos4r2zod and michalpolko

Some spells are not implemented yet, so you will need some custom fixes for them to see if the patch works for them.

All buffs and debuffs from here should be now working properly plus some more auras.

Patch will be developed here if I find any new information about what is still to be fixed. Track history of this file to see this patch development history.

I need some feedback, so please test and review

Update. Made some cleanup and fixed spell casting speed stacking and typo. thx to tibbi for testing.

[05-15-2011] Update2: corrected the bit flag check [as16].

If somebody is using mangosR2 fork and wants to use this patch for stacking auras: https://github.com/mangosR2/mangos/tree/aura_stacking

And patch on clean mangos core: https://github.com/michalpolko/mangos/tree/aura_stacking

Currently it should work very well, most aura effects stacking should be handled, there are only a few dirty hacks, stacking of holders is probably properly checked.

One last thing to do and research: more then 1 casters should be sharing 1 aura holder with stack amount > 1? Example: Sunder Armor and 2 warriors.
