Passive - Steam Powered Soul: Moving, attacking, and taking damage builds up Steam. The more damaged Blitzcrank is, the faster he builds Steam.

• Emergency Release: When Blitzcrank receives damage which brings him below 20% maximum health his hull cracks open and he rapidly expels his Steam for a few seconds. He knocks away every enemy around him and becomes clouded in Steam, camouflaging himself and his allies in the cloud of Steam. Enemies who enter the Steam gain vision of Blitzcrank, and any of his allies in the Steam, but their vision is reduced and they lose shared vision.

Q - Rocket Grab: Blitzcrank releases some Steam and fires his right hand in the target direction, pulling the first unit hit to him, stunning them for half a second. The distance is increased based on the amount of Steam he has built up. Any damage or spell effect an allied unit would take, while they are being pulled or are stunned, is diverted to Blitzcrank instead.

W - Steam Powered Fists - Toggle: Blizcrank begins consuming Steam as he starts rapidly punching in front of him, dealing physical damage and applying on hit effects with each punch in a cone in front of him. The longer this ability remains active, the faster he punches, with no cap on his attack speed. When this ability is toggled off or Blitzcrank runs out of Steam, he is briefly disarmed.

E - Gathering Protocol: Blitzcrank opens his intake vents and gains bonus movement speed for several seconds, building Steam twice as fast. While Gathering Protocol is active, Blitzcrank Cleanses allies he touches, as well as destroying any lingering enemy spell effects. When this ability ends, Blitzcrank is briefly slowed. (EG. Cassiopeia's Miasma, Singed's Poison Trail, and traps, but not active effects, like Anivia's Glacial Storm, or terrain like Trundle's Pillar of Ice)

R - Electric Heart- Passive: While Static Field is off cooldown and Blitzcrank is in combat, he fires a lightning bolt at enemy units within a 450 radius every few seconds, dealing Ability power magic damage, prioritizing Blitzcrank's attack target. Every basic attack, including those of Steam Powered Fists, decreases the cooldown of Electric Heart by a small amount.

• Static Field: Blitzcrank detonates his static field, dealing magic damage to nearby enemies and silencing them for a second.
