Master of the Maisters
Very rare4.6%Acquired every maister's teaching.
Twelve teachings across the ten vocations - Thief and Sorcerer have two apiece. Each comes from that vocation's maister, usually behind a side quest, and several sit on timers or share the same quest items, so grab them as they surface rather than banking them for later. The catch that trips everyone: owning the tome isn't enough - you must actually READ (use) each one from your inventory, and only then does it tick over. Watch the "Spellbound" forbidden-books quest in particular (it feeds the Mage teaching and one of the Sorcerer teachings, and the books are finite), and note the second Sorcerer teaching comes from Myrddin at Checkpoint Rest Town. Warfarer is worth unlocking early (155963981) as it makes gathering the rest simpler. Recoverable in NG+ if you slip one, but far less painful in a single pass. The checklist covers all twelve.
