Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is my first build so give constuctive criticism and some feedback.
After playing Sion you realize how many differnt ways to build him. I believe AP sion is most overlooked from what I have seen. Sion is very dangerous to begin with, he has a stun, a shield and an ability to give himself heaps more attack damage for a tiny amount of health. The only real downer with sion is his passive which does the equivelant to nothing.
Let's start with his First ability Cryptic Gaze. This ability is quite a mana ***** at the start of a game but it has good damage output and it has a 2 second stun which doesn't increase but it should be used wisely not as a harass. The stun is extremely useful and you will find you will be relying on it for chasing and intiating ganks and general fights.It also can provide some cool kills near turrets like all snares.
His second ability Death's Caress is one of the best shields in game and as a added bonus you get to blow it up when youve soaked up enough damage. Always turn this on when about to go into a fight because three reasons. The first reason is that nearly all nukers use the main damage burst at the start of a fight. The second reason is that if its one on one you can have a quick detonate so as to kill the person before they run away. The third reason is enemies might flee instead of fighting when they see your shield up if they know what it is.
Third ability is Enrage which provides more attack damage at the cost of a tiny amount of health. This is affected by ap at all so you only need to get it once at the start of a match if you want.
His Ultimate Cannabalism is alright but isn't affected by ap. You might not even bother getting at lvl 6 if you want to quickly lvl up your first two abilities. It just gives you attack speed and lots of lifesteal for a short time. Sometimes in a game I won't bother to lvl this up at all because it just isn't useful in this build.
Rod of Ages on Ap Sion=Ownage
Boots are your deceison depending on the way the fight is going.
Then go for sheen and build it to a LichBane
The next items are also subjective.Depending on the fight you might want more defense go with Guardian Angel and Banshee's veil. For Offense go with Guinsoo's Rageblade, Nashors Tooth and then the best item for late game sion is a zhonyas ring which makes his shield quite a ***** to get through.
The main strategy with Sion in combat is to shield up, stun, hit a few times then detonate your shield which will kill almost anyone late game but that is your general combat strategy with a 1v1 or 1v2 sometimes. In team fights you want to disable the dangerous people like the fed ryze so you can gang rape him do this with your cryptic gaze. Do not initiate fights because you are not a tank let the tank do that, if you dont have a tank you can shield and provide a distraction for a short amount of time but then you get out. With Sion always target the overextender and stun and rape. You can also do that when they are attacking turrets, stun then watch the pain.
Well they are a very personal choice and considering i havent bought any i can't judge what you chose. Thats right I'm not Lvl 20 yet only 19.
Ghost is pretty handy in this build considering we don't get boots till later than normal so its good for escaping and chasing.
Ignite is great for the extra damage early game and gives some AP while its recharging if you chose it in the masteries.
Other good summoner spells would be Exhaust too add that extra immobilization guaranteed to piss opponents off. Teleport is always handy, Cleanse is alright and Clarity. Heal is terrible past the first few minutes with Sion. Flash would be alright as well.
It is your choice the summoner spells in this build are my own opinion of what works best, please feel free to toss that aside like everyone else.
As i said this is my first build so give some feedback on how it works for you.
Thankyou for reading.
