Q: Grappling hook ACTIVE: Blitzcrank fires his right hand in the target direction, tethering to the first enemy hit applying a slow for 10% for 1 second, after 0.5 seconds of contact Blitzcrank can reactivate Q to pull in the target dealing magic damage. If after 1.25 seconds the target is not pulled or moves too far from Blitzcrank the hand releases and the tether retracts.

R: Oil Slick PASSIVE: Blitzcrank leaves a short trail of oil behind him increasing in width and length as he levels up which slows ALL entities that traverse across it.

ACTIVE: Blitzcrank dumps his oil reserves to create an oil field which slows enemies that enter it by 40% for 1.5 seconds, if enemies remain within the field as it dissipates they are stunned for 0.5 seconds. Oil reserves can only be replenished upon visiting the fountain.
