Q: How do items work? Do they stack?

A: All stats from items will stack additively except for those that have a UNIQUE ability. For instance, the Infinity Edge item has the following stats:

+80 DMG
+20% Crit
UNIQUE Passive: Critical hits now deal 250% damage instead of 200%.

If you were to pick up two Infinity Edges, you would have the following stats:

+160 DMG
+40% Crit
UNIQUE Passive: Critical hits now deal 250% damage instead of 200%.

Note that both the damage and critical chance stack additively, but because the passive to the Infinity Edge is UNIQUE, you cannot be affected by that more than once.


Q: How do item auras work together?

A: If you and a teammate both have the same item, you will be affected by the aura twice. As an example, at the start of the game you purchase Mana Manipulator. This item gives a mana regeneration to yourself and allies nearby. If you were to go with a teammate who also purchased Mana Manipulator, both of you would be affected by this aura twice.

However, if you had a third teammate that did not have the Mana Manipulator they would only be affected by one aura.

Note that you can be affected by the same aura at most twice. Once if you have it, once if a teammate has it.

What is the range on item's auras?

Just to save you some time, it's not actually in the game's files as far as I can see.

Stark's Fervor doesn't stack.
Touche Riot.

A mention about CDR stacking should be made

Brief mention on On-Use, On-Hit, etc?

Wardens mail is not a unique passive, does it stack?

so 2 warden's mail give you 40% (additive) chance so slow or only 36% (each has a separate chance to slow, ie: multiplicative)?

Ok I just checked and it stacks multiplicatively (ie: every time you get hit, each warden's mail is tested separately), as I had 5 of them and it did not proc 100% of the time.
