This is my build for defender Blitzcrank.
According to me, Blitz is one of the best deffenders out there and taking a point from him is very hard if he is played correctly.
I will not go in on all the details on Blitz in this guide.
Their are other guides for that. For example B.B.B by BB -- Beginners Build for Blitzcrank is a great guide for Blitzcrank. Look their if you want a closer look of Blitzes skills.

What you will get from this build however is an insight in my strategy and a good itembuild for Blitzcrank on dominion.

PLEASE don´t downvote right after watching just the items and going: OMGZZ NO DAMAGE ITEMZZ N00B!, try it out. You don´t need damage since the point will do all the damage for you.

PROS:

Alot of CC.
Great baiter with his shield and the heal.
A grab to drag people into the point.
Alot of CC.
A speed buff.
A passive on your ultimate that attacks even when you are running.
Alot of CC.
Is a robot.

CONS:

No sustain, making the summonerspell heal almost a must.
Melee.
Might be hard to hit the grab without some practice.
Irritating voice.

Can´t come up with more cons. Blitz is just a really good champion for this role.

The city of Zaun is a place where both magic and science have gone awry. The unchecked nature of experimentation has taken its toll on the city. However, Zaun's lenient restrictions allow their researchers and inventors the leeway to push the bounds of science at an accelerated rate, for better or worse. It was under these conditions that a team of doctoral students from Zaun's College of Techmaturgy made a breakthrough in the field of intelligent steam automation. Their creation, the steam golem Blitzcrank, was developed to exercise judgment on-the-fly in order to assist with Zaun's hazardous waste reclamation process, since so often the conditions did not allow for human supervision. However, he soon began exhibiting unforeseen behaviors.

Over time, the scientists were able to identify a demonstrated learning process, and Blitzcrank fast became a celebrity. As is sadly often the case though, credit for the golem's creation was scooped up by another - Professor Stanwick Pididly - though most now know the truth. In the wake of the ensuing legal maelstrom, it became evident that neither party truly had the steam golem's best interests at heart, and Blitzcrank humbly petitioned for personal autonomy. Backed by overwhelming support from the public, it took the liberal Council of Zaun only a few weeks to declare Blitzcrank a fully-independent, sentient entity. A unique being, the golem left Zaun, distressed by the controversy and feeling there was no place he could fit in. His travels led him to the one location in Valoran where unique beings have a place - the League of Legends. Fortunately, he was easily able to adapt his design to suit the rigors he would face on the Fields of Justice.

Though Blitzcrank may batter anything that stands in his way, he really has a heart of gold...encased in a framework of iron...in a carapace of steel.

My thought with this build is that when the enemy champions are running to take your turret, you just grab them, knock them up and just make them unable to reset the point. When they starts to target you, just activate your W and run around.
Use garrison on the point and keep knocking them up, grabbing them and silencing them with your ultimate.
The point shoots at them and you will end up with doubble and tripplekills.
When your life gets low you just use your heal.
I have not included any damage items, except for the Frozen Mallet, which still is more for the slow and health.
Just let the turret do all the work for you!

Remeber that sometimes it´s better to hold on to the active part of your ulti and let the passive effect do what it does best, damaging while you are running around.

When to use it:

-You will get a kill out of using it.
-Silencing AP characters or skilldependant characters with skills that can mess up your
tactic.
-There are 2+ champions trying to take the point.



You are best of defending the TOP point. That is the most important point to keep in dominion, since it´s the furthest away from both teams base. Taking points close to the enemies base makes it easier for them to take it back, since they can just go back and heal!

P.S
If you want to troll a bit, capture the point closest to their base and see how long you can keep it!

The build above gives you all the CDR you need and also make you very tanky.
Ofc, in some games you need to adjust.
Full CC team? Get Merc Treads!
Almost their whole team are AD or your facing a fed Tryndamere? Get Thornmail instead of the Force of Nature.
And if their whole team are AP, then don´t get a Frozen Heart.

But the items above is what you should usually get if they have a well balanced team.

Basically R-E-W-Q

You only really need Q for a grab and not any damage. The CDR you get by leveling up this skill is good, but putting points in E and W is much more important.

Max ulti whenever you can. It´s just a great ability.

I max E first after ulti because of the great cc it gives. It´s a knockup so it´s not even effected by Tenacity and you want to be able to use it as often as possible.

W is maxed second because of the increased movementspeed. When you are running around inside the turret and making the enemy having to chase you around while taking damage from the point is very powerfull.

After that you complete with leveling up Q.

That´s a picture of my recent games with Blitzcrank.

I hope you like this build and strategy with Blitzcrank, all our favourite robot.

Don´t downvote until you have tried it out, and if you do, leave a comment to why you didn´t like it.

Good luck!
