This build mainly utilizes Vorpal Spikes. I've been using this build a lot lately. It started as a jokey build and I realized it actually works really well. The main focus, besides the obvious health and size building, is Auto Attack damage.

You're going to start with your E. It sounds weird, I know. Early game Cho has barely any mana, so I find myself just using the Spikes to farm and harass. Max E, R, Q, W in that order. Think of Q and W as late game CC tools only.

I spend the first ten or so minutes of the game just passively farming. The basic rule I follow is this: the enemy laner barely exists. Don't go out of your way to try and harass unless you are 100% positive you will get a kill, and even then don't do it unless you have a Feast ready or a confidant Jungler. Focus on last hitting, wave clearing, and feast Melee and Cannon minions whenever you can. Whenever you have 2700 gold saved up, go back and spend it on RoA. Now you may do as you please. THE HUNT BEGINS.

Pros:
+ Late game you are nearly unstoppable
+ You have a ton of HP to tank with
+ Your pushing power is amazing
+ You can do decent damage when you need to
+ You can auto-attack someone to death

Cons:
- Your Q and W don't do much damage
- Your lack of boots makes you pretty slow
- You're passive until late game
- Cooldowns are long (which is why I utilize the vorpals)
