Playing as Jayce
Tips to maximize your impact
- 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.
- 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).
- 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.
- 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
- 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.
- 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.
- 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.
- 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.
- 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.
