Fishbones

Fishbones is Jinx's rocket launcher: a huge, shark-styled weapon she built by combining her minigun and her rocket launcher, and which she hauls around as if it weighed almost nothing. Its rockets are chemtech-powered, like her flame grenades, and the design goes back to sketches she made as a child. Powered with a Hextech crystal, she fires it into a Piltover Council meeting, killing three councillors and severely injuring others, and the blast wrecks the Council Building.
