Okay so 
gives 20% LS but it says UNIQUE passive, meaning the lifesteal from a 2nd wouldnt make it 40.. HOWEVER, 
passive 12% lifesteal isn't unique, so this would mean i could build 2 's for 24% LS?
So this: should be better than this: if one were to opt for this crazy build, yes?
EndlessSorcerer4 votesUnnamed unique passives can be stacks so long as they are from different items.
+ 
= 20% CDR
+ = 10% CDR
Named unique passives cannot stack, but may combine certain attributes of each (i.e. Spellblade).
+ 
= TF's damage dealt to single target, IBG's AoE damage and slow around target (not affecting the primary target)
+ 
= Whichever burn does the most damage will be applied, the other won't.
For your example:
+ = 24% lifesteal (since it's not unique)
+ = 20% lifesteal (since it is unique, they don't stack)
+ = 32% lifesteal

ImTheRealGnar2 votesYes it would be better
Penns2 votesYeah, you should only get one , but life steal from stacks.
You probably shouldnt stack any of them but hey :p
Posui Gart1 votesWell, yes, you can stack hydras for lifesteal. But that build will have no AS and crits, so if you are building lifesteal-based build-at least add Botrk and a crit item

ayyyyy
BuzzinTate1 votesactually lee sins passive lifesteal would make better with this kit (my opinion) 
Dreadlocks1 votesFull damage makes his abilities do a lot too not just focused on the 2nd W autos. Q scales 90% bonus AD, E 100%AD -> magic R 200% bonus AD but u raise an interesting option friend xD
sounds like a fun build too lol.
