Jinx swaps weapons.
Fishbones, the Rocket Launcher: Basic attacks deal 110% Damage to the target and nearby enemies, gain 100/125/150/175/200 range, drain Mana, and scale 10% less with bonus Attack Speed.
Pow-Pow, the Minigun: Basic attacks grant bonus Attack Speed for 2.5 seconds. This effect stacks up to 3 times for a total bonus of 30/55/80/105/130%. Stacks fall off one at a time and only benefit Jinx's first attack after switching to Rocket Launcher.
