Azir is The Emperor and will not be stop till his kingdom is back from the sands. Though I don't know why he's a birdman.

The story behind everything this..man I guess is superb, with powers flying around and demi gods helping, betrayal, and new enemies and allies decades after.

Greater Seals x9 Magic Resist
Greater Marks x9 Magic Penatration
Greater Glyphs x9 Mana Regenaration
Greater Quints x3 Cooldown Reduction

Concentrate your points on cooldown's, mana regen and magic penetration. Also if you can AP isn't bad to have either

Cooldown's, AP are a must and that will reacted with his passive, movement speed isn't that bad either.

obviously you can only get you W first then get your Q then E and upgrade your ult when you can.

Max your Q first then your W and finally E.

Flash because Flash.
& get exhaust too because both of these put together will ruin the lives of anyone who apposes teh emperor of sharima.

So basiclly both flash and exhaust will get you out of trouble and into it, working it with your W,Q,E combo will get the thrill of the chase.

Pros
He's a snowball
can play as APC not just a laner
passive turret
great crowd control with his soulders
very powerful mid game

Cons
Very item Reliant
Hard to play as without practice
Early game below lvl 3 easy to get killed
though a snowball hard to get it started
