Tibanna was excreted by Beldons, huge gas-filled creatures. The gas was a by-product of the vapors consumed by Beldons. Tibanna was extracted from Bespin's atmosphere as atmospheric gases rose on updrafts through Cloud City's unipod. The gas was then processed and packed in carbonite for transport off-planet. Tibanna gas produced four times its normal energy output when cohesive light passed through it. Thus, when spin-sealed (compacted at the atomic level), Tibanna was used as a conducting agent in blasters and other energy weapons, producing greater energy yields and thus greater amounts of damage. Most personal weapons could not tolerate this power boost, but ship-mounted blasters benefited greatly from the use of Tibanna gas. Exceptions to this rule were the DC series rifles of BlasTec
