Playing as Jayce

Tips to maximize your impact

  1. Poke through your gate

    In cannon form, fire Shock Blast (Q) through Acceleration Gate (E) from the start of lane: the orb gains speed, range and damage, and it's your best poke.

  2. All-in with the hammer

    To all-in, switch to hammer: leap in with To the Skies! (Q), activate Lightning Field (W), then knock your target back with Thundering Blow (E).

  3. Auto after every swap

    Land an auto after each weapon swap: switching to Mercury Cannon (R) reduces your target's armor and magic resist, and your first hammer hit deals bonus magic damage.

  4. Swap weapons to escape

    To escape, swap weapons then walk through Acceleration Gate (E): Hextech Capacitor (passive) and the gate each give you move speed.

Playing against Jarvan IV

How to counter and exploit weaknesses

  1. Step out of his flag's line

    As soon as he plants Demacian Standard (E), step out of the line between him and the flag: Dragon Strike (Q) pulls him to it and knocks anyone in his path into the air.

  2. Punish him after his combo

    Punish him after his flag-and-lance combo: without the flag, he has no dash to get out, and Demacian Standard (E) has a 12 to 10 second cooldown.

  3. Save a way out of his arena

    If you have a way over walls, save it for Cataclysm (R): the arena can't be crossed on foot and locks you in with him while it lasts.
