Why Conqueror
Conqueror's ramping damage in extended duels is perfect for Jax's auto-attack based fight pattern, allowing you to pump out massive damage over time.
Why Triumph
Jax is a solid **tower diver** and Triumph's big heal can make the difference between life and deal in sticky situations.
Why Legend: Alacrity
All of Jax's damage comes from his ability to auto attack repeatedly and Alacrity helps your early game trades and skirmishes massively before you're able to build any significant Attack Speed. It also allows you to opt into more defensive items so you can prolong the trade.
Why Coup de Grace
Your rune choice here largely depends on if your laning against a tank or not. Coup De Grace is good at killing squishy champions. If you *are* laning against a tank, take Cut Down.
WhyMagical Footwear
Magical Footwear's raw mid-game gold value accelerates you into a quicker 2nd item power-spike.
WhyTime Warp Tonic
Time Warp Tonic pairs well with with your Corrupting Potion start for strong dueling.
