Lethality Jayce build with runes and items. Lethality Jayce guide offers in-depth how-to play, skill order and tips. Play Lethality Jayce build in League of Legends Patch 25.05!
Snowball / Mark is a crucial cooldown for playing this build. Do not waste it or even wait to hit the enemy at point-blank range to ensure hit (so you follow them, if they Flash).
If an enemy team is full of tanks or bruisers, rush Serylda's Grudge or even Lord Dominik's Regards early (sometimes even #2). Black Cleaver is also an alternative. The key is to adapt to the enemy team.
Tips and Tricks
Champion
Your usual combo is To the Skies! / Shock Blast (Q), then Thundering Blow / Acceleration Gate (E) (not E then Q!). You first use Q, people do not expect that it will go further, and then you enhance it mid-flight with your E.
As Jayce, you have your 'Ultimate' Mercury Cannon / Mercury Hammer (R) since lvl 1. You can lose track of enemy levels and get surprised by their level 6 spike and their ulti. Watch out!
Cannon and Hammer Form interactions
Jayce is treated as melee in Hammer Form and as ranged in Cannon Form. That means there are interactions with certain runes and items. Examples below.
Grasp of the Undying - If you want to deal more damage, get more Health and heal for more with Grasp of the Undying - when auto from ranged, switch to melee (when animation is mid-flight)!
First Strike - If you play Jayce with First Strike rune, if you fire Cannon To the Skies! / Shock Blast (Q) and change to Hammer Form, you actually get the melee gold. This way you can farm and earn additional gold (up to 100-150g per minute) by coordinating E + Q with First Strike.

Hubris - if you score a takedown when in Hammer Form, you get more Attack Damage (melee effect), than you would get in Cannon Form.
Riot
Be sure to switch stances often. It will enhance your attacks and grant you quick bursts of speed.
If you find yourself taking lots of damage, try using Jayce's Hammer Stance, as it grants you additional defenses.
For increased range and damage, try casting Shock Blast through the Acceleration Gate.
