The Cosmic Dust Omnibus is a legendary tome that can crafted at the Crystallogy Workbench. It produces 5,000 Cosmic Gem Dust when it is fully charged. Unlike Common Tomes (that can be used repeatedly without cooldowns), Legendary Tomes can only be used once a week, although they provide more rewards than Common Tomes per individual use.
