Certain items stack while others do not. It would be nice to know which items have this effect. EG: Rageblade: Unique Passive: Attacks grant 3% Attack speed. Stacks infinitely. Locket of the Iron Solari: Passive: On start of combat, all adjacent allies gain a shilled of 200. Thank you! -GloriusEvloution
By a rule of a thumb all passies stacks with exceptions.
Phantom Dancer doesn't stack (technically it stacks but the effect just isn't going to improve when it is already 100% chance to dodge crits). Rapid Fire Cannot doesn't stack (same deal, but maybe the range stacks - should be noticeable on melee champ? Confirmation needed.
I've definitely seen multiple items stack. The phantom-dancer like items pretty obviously don't stack because they don't change the previous status the first item had.
However, what I don't know is whether chance items stack, like if an item says "small chance enemy will be reduced 1 level". If that chance is 5%, well, does stacking 2 give you 10% or 5%?
