Hello there! We are Bowero and darkwes, and we're writting thé build for Sion. Stun -> Kill :)

We are focussed on agressive gameplay so you can enjoy the game and don't have to worry because it are all free kills! Be aware! Full YOLO and on own risk! (But it worked fine for us)

Good luck!

(If you want to see the latest score before posting this (Yeah, we were not ready yet, but **** that):)

Pros Fast wave clear Extremely much lifesteal (so durable) His passive can say if it is life or death Damage.

Cons Bad magic resistance Without boots or masteries he is very slow His shield has cooldown before trigger Bad CC

Long Sword This item is great to begin with because you can upgrade it to everything that deals damage :D
Health Potion Yeah, we just don't want to go back, and your E uses health
Stealth Ward Just, because.

Infinity Edge Why do I take this item twice? Just because it is awesome. 50% critical strike chance and 140 attack damage total.
Ravenous Hydra It helps our E to stack more health. And we want penta kills, so AoE is needed.
Phantom Dancer Critical strike and attack speed makes a wave clear easy and fast. So that's the same with champions. Clear or ignore.
Statikk Shiv For the extra wave clear, the scary start when you rush in and the extra ciritcal strike chance, and of course, the movement speed is very handy.

Boots, just because the game becomes so long else. If you aren't in a lane to kill the enemy, it will never be done. You can choose a lot of boots, but this are the boots we advice

Mobility Boots To follow your enemy when they are low or, what we don't want, but can be handy, to run away (only when needed!)
Berserker's Greaves The attack speed bonus on these boots is also very handy
Ionian Boots of Lucidity Cooldown reduction. That's enough argumentation.

Furor is an essential enchantment.

Start with your Q to save yourself in early game or to get the first blood. After that, you just start maxing your E with sometimes a W. Your W is important for AoE damage and saving your butt in teamfights.

Lets hold it short. For big minion waves first activate your shield and then trigger it, clear the remaining with your basic attacks, combined with ravenous hydra. If you only want health on your E, don't trigger your shield too late.
