Hex missile
From Wookieepedia, the Star Wars wiki.
Hex missiles were projectile missiles containing an special warhead armed with the chemical weapon trihexalon, also known as Dragon's Breath. Captain Cavik Toth deployed Hex missiles against the natives of Maramere prior to the Clone Wars.
Captain Toth had Hex weapons forged in the foundry on Nod Kartha, and ordered Lieutenant Bella to test them against the Point Modai settlement on Maramere. Hex missiles rained down upon the island from orbit, though fortunately for the Mere, Jedi Master Adi Gallia was able to destroy them before they reached Point Modai. Nym later led the strike force that destroyed the factory on Nod Kartha.
With his last reserves of Hex missiles, Cavik Toth launched an attack on the Republic forces fighting on Geonosis, sending Hex Deployers and bombers towards the surface. Once more, Adi Gallia was able to intercept and destroy all missiles launched at Geonosis, before eliminating Toth and his flagship.
