Hi, you are playing one of the most OP stronk mid champs, What do you do?

Self explanatory

Maximizes CDR with utility.

Why not Furor Boots?
It is generally better to have a flat movespeed increase with Alacrity, or a huge fountain boost from Homeguard to get to your lane faster/roam.

The item build isn't done as you can see, because its entirely situational after that.

Some items to consider:

Abyssal Scepter
Warmogs
Void staff
WotA
Liandrys torment
Banshees Veil

Having ulti while farming jungle is recommended, although it isnt needed

After you get cdr from Glacial Shroud(which you should have 35%~ cdr), you should be using your Q inbetween every other spell to fully utilize his passive

Pros:
Has a triumphant ryze skin which is great

Cons:
Triumphant ryze is riot-sponsored-controlled

Horrible AA cser, bad mana sustain early game, but mid-late you should be fine

After you get your tear you should aim at farming with your Q if you know you have enough mana for other situations

Aim at staying near the back of a fight like a normal AP carry would do, make sure you spam all your spells

A Great safepick
Great CC
Great AOE in teamfights
High sustained damage

A Great champion all around for competitive play.

Why not choose Ryze?
