The Arch-Mage's Boon is a quest available in The Elder Scrolls Online.
- Speak to Arch-Mage Shalidor outside the Mages Guildhall.
- Although the level requirement is 50 for this quest, it starts as soon as you've spoken to Shalidor after deciding Valaste's fate in the previous quest. This means that its possible to complete this quest at level 30.
Eidetic Memory will sometimes not unlock all the books already read - for example, the "Chronicles of the Five Companions" books.
