Blitzcrank is a champion with one of the game's most powerful and iconic abilities, but because of this he's also been stuck as a one-trick pony: he's the absolute best at pulling enemies away from their allies, but that's pretty much the only thing he can do, and he can only do it in pretty much the same way. Additionally, due to him originally being designed as an AD / AP hybrid solo laner and jungler, there's a lot of power on his kit that's just not that useful most of the time, such as the attack speed on Overdrive or the passive on Static Field.
Niche - The weaponized warehouse robot. The forklift. The organizer.
Lore - Blitzcrank was designed to be an automated replacement for the general workforce of Zaun, but his design was overqualified for slave labour and decided to do what it wanted.
Base mana increased to 300 from 267.2.
Mana growth increased to 70 from 40.
I - Mana Battery
COOLDOWN: 90 seconds
New Innate:Blitzcrank stores all mana he expends as grey mana. If Blitzcrank drops below 20% of his maximum health, he converts all of his grey mana into a shield that decays over the next 6 seconds. If out of combat for at least 5 seconds, Blitzcrank will rapidly consume his grey mana and restores mana equal to 25 / 35 / 45 / 55% of the grey mana consumed.
Q - Rocket Grab
COST: 100 mana
COOLDOWN: 17.5 / 15 / 12.5 / 10 / 7.5
Active:Blitzcrank fires his right hand in the target direction, pulling the first unit he hits and, if enemy, dealing them 60 / 95 / 130 / 165 / 200 (+ 50% AP) magic damage. The target is not stunned during Rocket Grab.
Blitzcrank must spend the time to retract his fist even if he does not hit a target.
W - Overtime
COST: 75 mana
COOLDOWN: 21 / 19.5 / 18 / 16.5 / 15
Active: For the next 6 seconds, the cooldown of Rocket Grab and Power Lift is reduced by 80% (doesn't stack with CDR) and he gains 70 / 75 / 80 / 85 / 90% bonus movement speed. The bonus movement speed decays over the duration, but the strength is refreshed whenever Blitzcrank damages an enemy champion. At the end of the duration, Blitzcrank is slowed by 30% for 1.5 seconds.
E - Power Lift
COST: 50 mana
COOLDOWN: 9.5 / 9 / 8.5 / 8 / 7.5
Active:Blitzcrank locks his hands together for the next 0.75 seconds then flings all units—both allied and enemy—in front of him overhead, dealing 60 / 95 / 130 / 165 / 200 (+ 50% AP) magic damage to enemies.
R - Electro-Magnetic Position Adjuster
COST: 100 mana
COOLDOWN: 140 / 120 / 100
Passive:Blitzcrankcharges champions he hits with his basic attacks or Rocket Grab, up to one at a time. Charged units are immune to Electro-Magnetic Position Adjuster.
Active:Blitzcrank gathers energy for 1 second before engaging a powerful electro magnet that captures all surrounding units, locking them in geostationary orbit around Blitzcrank for 1.5 / 2 / 2.5 seconds. The electro magnet will power down early if Blitzcrank dies.
