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 Kayn

How to counter and exploit weaknesses

  1. Dodge his Blade's Reach

    Dodge Blade's Reach (W): Umbral Trespass (R) can only target a champion he just damaged, and this ranged hit is how he marks you from range.

  2. Save your CC for his E

    If you have CC, land it during Shadow Step (E): once immobilized, he loses the spell and can't move through walls anymore.

  3. Save your spells for his exit

    Don't cast your spells during Umbral Trespass (R): hidden inside your ally, he's untargetable. Save them for when he bursts out.

  4. Ward your jungle too

    Ward your jungle too, not just the river: Shadow Step (E) lets him go through walls and show up from unexpected paths.

  5. Pressure him before he transforms

    Pressure him before his transformation: until he picks Rhaast or Shadow Assassin, The Darkin Scythe (passive) gives him no healing or bonus damage.
