New main objective: Bring the Four Master Illusion texts to Drevis Neloren
Note! This quest is optional and you will get the chance to approach it no sooner than after raising Illusion to at least 90 points.
In order to activate this quest, you will have to find the mage Drevis Neloren and ask him if he can teach you anything more about Illusion (screen above). Note – If you don’t see this option, it might be a bug and in this case you will have to raise Illusion to 100 points. Drevis will offer you read information about powerful Illusion spells found in the books hidden throughout the College, In order to find them, you will have to use the newly unlocked Vision of the Tenth Eye. You will be asked to use it to find four books.
Press TAB, head to Magic, Illusion and set Vision of the Tenth Eye as active. From now on you will be able to use this spell which doesn’t cost any MP at all, though you will have to re-cast it from time to time. Head out to search for the hidden books.
The first book titles Master Illusion Text can be found on the upper floor of the Hall of Countenance, to be precise in the storage room in the south-east part of the tower (screens above). Approach the book and press E twice, as you not only have to open it, but also take with you.
The second Master Illusion Text is at the upper floor of the Hall of Attainment, below a bench beside the stairs (screens above).
The third Master Illusion Text can be found at the Arcanaeum, on the table in the western part of the library (screens above).
In order to reach the fourth and last book, you will need to head to the Midden by, for example, using the hatch at the College of Winterhold square (screen above). More information on reaching the Midden and the fights awaiting you inside can be found in the description of the Good Intentions main College quest.
Explore the eastern part of the Midden. The Master Illusion Text can be found on a table nearby The Atronach Forge (screens above).
You can now return to Drevis Neloren and give him all the books that you found (screen above). The main reward for completing this quest is the Spell Book: Hysteria, allowing you to learn a new powerful spell. Apart from that, Drevis can sell you other precious books, namely Spell Book: Harmony, Spell Book: Call to Arms and Spell Book: Mayhem.
