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.
Start - Get meki pendant and 2 health pots
Early game: I would typically lane bot/top with another stunner, Hook/fist exhaust if needed, most likely you will get a ton of assists for this.
When you can, get either a chalice or philosopher's stone and ninja or mercs. typically it would depend on who i am against. Lots of physical attacks - go with tabi, lots of casters or stuns/slows - go with mercs. Also, I would get philosophers if i was getting hit a lot in my lane, otherwise i would get chalice for the magic resist.
After this point, start working on RoA, you should have it by around 22-25 minutes.
Next item you want to work on is either frozen heart or banshee's veil. Once again, depends on preference/situation at hand. Which ever one you didn't get, get that next or get the warden's mail if you're going against a lot of physical attackers. I sometimes will get the spirit visage if I have a strong healer on my team.
Team fights: you basically just take hits and stun. Hook/punch, then overdrive. Exhaust if there is a serious physical threat on the other team. If you get stunned, use cleanse.
When to use your ultimate. Many people use this incorrectly. Use it if you are confident you can get the kill blow on an enemy. The passive on it does serious damage, and you should try to keep that passive up for as long as possible. If you're in a team fight it also isn't a bad time to let your ulti loose. When chasing someone, save the ultimate until the end.
Hooking: What many people don't realize is how incredibly large your hook really is. Your hook can reach far outside what the radius really says, about a good 3/4 inch outside the range.
The CD reduction helps a ton because you will be able to hook/punch more frequently. Also the dodge is nice because, obviously you will dodge more often which is nice for a tank, but also you will get 10% increased movement speed, so you can chase enemies easier.
Feedback is nice but please realize, this blitz is not meant to be doing damage, he is merely just stunning and tanking. So AP, attack damage, and attack speed are not important to me, hp/mana (mana shield passive is amazing), cd reduction, MR, and armor or what matter to me.
Not that it means much, but during his rotation, i had my k/d/a at a 2/1/3 ratio.
