- Firstly, this is my first post so I'm sorry if there is anything wrong with this one.
- Secondly, I am a Vietnamese and I don't speak English much so I'm sorry for my bad English.
- Thirdly, some of you might think this build is troll or something like that, but just test it. When I use this build, I am like 2 - 4 - 35. ( Blitzcrank OP)
- Fourthly, it is easy to ks with this build for Blitzcrank so be aware.

Blitzcrank is a supporter which can cause big mutations with his Q - Rocket Grab. He brings high pressure to his enemy from Early game to Late game. Blitzcrank so OP.

Mana Barrier

When Blitzcrank's life is brought below 20% health, he activates Mana Barrier. This creates a mana shield equal to 50% of his mana for 10 seconds. Mana Barrier can only occur once every 90 seconds.


Rocket Grab

Cost: 100 Mana
Range: 925

Blitzcrank fires his right hand to grab an opponent on its path, dealing damage and dragging it back to him.
Blitzcrank fires his right hand, if it encounters an enemy unit it will stun them and deal 80/135/190/245/300 (+100% Ability Power) magic damage while he pulls them to himself.

Range: Self

Blitzcrank super charges himself to get dramatically increased Movement and Attack Speed.
Blitzcrank supercharges himself to increase Movement Speed by 16/20/24/28/32% and Attack Speed by 30/38/46/54/62% for 8 seconds.

Cost: 25 Mana
Range: Self

Blitzcrank charges up his fist to make his next attack deal double his total attack damage as physical damage and pop his target up in the air.


Static Field

Cost: 100 Mana
Range: 600

Passively causes lightning bolts to damage a nearby enemy. Additionally, Blitzcrank can activate this ability to damage nearby enemies and silence them for 0.5 seconds, but doing so removes the passive lightning until Static Field becomes available again.
Passive: Lightning arcs off of Blitzcrank to hit a random nearby enemy for 100/200/300 (+20% Ability Power) magic damage every 2.5 seconds.
Active: Deals 250/375/500 (+100% Ability Power) magic damage and silences surrounding enemy units for 0.5 seconds. The passive is not in effect during the cooldown.

The masteries above will help Blitzcrank to have lower cooldown and his allies can cause extra damage to enemies. And he will be much more tanky.

Blitzcrank normal combo: Overdrive --> Rocket Grab --> Power Fist --> Static Field
