I decided I should finally start trying for the "get a tome" achievement, so I did Quentin's quests. Out of fifteen, I got one amulet. Took it to the mage, and bam:

Unlocked Mage Tome Recipient! Get a Tome from the Mage! Thank you for bringing me my amulet! You have been a great help! As promised, here is your gift:

Tome of Darkness

WELL THEN.

Congrats on the achievement!
