item ability stacking

[PrisonLove]

is there a way to make item abilities not stack? like if i want it to be so that only the dominant attack speed item gives you the attack speed bonus how do i do that?

example

item 1 gives 10% attack speed
item 2 gives 15% attack speed

how can i make so that if one unit has both items there is only a 15% attack speed bonus?

use the same aura/ability like copy the first and edit it then add it to the item.

so identicle abilities will not stack?

so lets say one item is attack speed bonus and the other is attack speed bonus (greater) they will stack together, but 2 attack speed bonuses wont?

Item Attack Bonus (aka gloves of haste) is stacking with each other. (with some formula I dont remember). One reason is because it doesn't have any aura/buff. So it wouldn't matter if you use 15% standard or 25%(the greater one)
Bash and Critical Strike works this was as well. Bash uses the "stun" buff I know, but that is another matter (it is rather an effect like the critical hit bonus).

If you take Item Endurance Aura as example, it wont stack with anything, not the normal Endurance Aura spell either. As I said above, non-stack occurs when they are based on the same buff/aura "act" code. (it will not even work if you use different buffs and well, that, I cant explain why...)
