this build is badly thought through.

needs Tri force + youmuu's.

does not need bloodthirster at all

needs magic resist

What level of gameplay do you play with this build ? I feel squishier than a kassadin. Sure I can get some early kills but midgame I get gang raped in 3 seconds once they see I have no health.

Although the damage looks impressive, it has very little armor penetration, no resists or armor, no health. A *good* enemy team will be able to shut this down easily. I recommend, at the very least, taking out an infinite edge and replacing it with trinity force. This will give you chasing ability and more attack speed, which is also lacking.

Never been a fan of AP sion but this AD works really well. Tryed it many times and the last game i went 11-2-8 hehe ^^ +1

Great build,once u get the bloodthirster its sooooo easy.... :D

I've tried this build several times and I've only gone negative once and this is coming from someone who just started using Sion in the same day! Around mid-game, you find you don't really need potions or recalling because your life steal just brings your health back up and your ready to go. Although, I might suggest carrying around mana potions because Cryptic Gaze and Cannibalism tend to take up alot of mana.

Addressing your skill-level chart, I would probably suggest that you level up Cryptic Gaze at levels 1 and 3 and Enrage at 2, 4, and 5. Other than that, the build and everything is simply perfect. Thank you. Thank you. Thank you. +1 for sure.

just wondering, when youre versing pro tanks, what item in your build do u think is most interchangable with like a madreds bloodrazor? great build btw +1

great build, although it might help to buy a tiamat to farm and i like to be the frozen mallet earlier to ensure you get those champion kills. great job though. +1

So...I see a humongous problem with this build and its the fact that you have absolutely nothing to protect yourself no type of armor or magic resist, any burst AP or carry with a madreds will eat you alive, I mean...instead of the wasted item space with Dagger you could get an Atma's Impaler or Warmogs armor, same for berserkers, could be used for mercs to help with CC and get a lil more magic resist...like your guide says the 50% attack speed+100% lifesteal boost from your ulti should be more than enough speed to handle a team, and if you opt out on your Black Cleaver (waste of an item in my mind, the armor reduction really isnt that helpful) you could update to the Hexdrinker which will make you a MACHINE in fights against AP champs

*Edit Note*With Death's Caress and Enrage active(which it always should be) you should have 0 problem man handling any jungle foe without building any lifesteal, you dont even really need the bloodthirster, 100% lifesteal on the ulti is really enough to heal you up whenever you may need it, 90 second cooldown isn't really that long of a time, you can run through the jungle, ulti on the last buff mob you encounter, come out fully buffed and your entire jungle side empty and at full health without using any lifesteal items, then a short 90 seconds later youll be able to push hard in a team fight if thats even the case

i love ur build went 27/6/5 yesturday. just one comment maybe you can get vampiric scepter after berserkers greaves for easy creeping and jungling. great build tho +1.

well my best with sion looks like that , 66 min they can't beat me :D

sheen sucks on sion, u have a 10-12 sec stun cd and 8-12 sec shield cd, so it is kinda useless^^
