Passive: Get Excited!
Jinx gains a massive movement speed boost whenever a champion or tower that she's recently attacked is killed or destroyed. This boost decays over time.

Q: Switcheroo!
Jinx swaps weapons:
Fishbones, the rocket launcher: Jinx's basic attacks consume mana but gain increased range and deal increased damage to her target and nearby enemies.
Pow-Pow, the minigun: Jinx's basic attacks grant attack speed for a short duration, stacking up to three times. Stacks fall off one at a time once Jinx stops attacking.

W: Zap!
Jinx snaps off an electrical blast that deals damage to and slows the first enemy hit.

E: Flame Chompers!
Jinx throws out a line of snare grenades that detonate after a few seconds, lighting nearby enemies on fire. Enemy champions who walk over a grenade will cause it to detonate early, rooting them briefly.

R: Super Mega Death Rocket!
Jinx fires a global rocket that gains damage as it travels. The rocket explodes on the first enemy champion hit, dealing damage to the target and all nearby enemies based on a percentage of their missing health.
