The Builderite Booklet is a Legendary Tome that can be crafted at the Crystallogy Workbench. They produce 35 Builderite when they are fully charged. Unlike Common Tomes (that can be used as often as you like without cooldowns), these tomes can only be used once a week, although, they provide more rewards than Common Tomes per individual use.
