Risen

Chapter 4 (Mage Only)

For this you have to play for the Order, as it involves learning the highest spell level, Seal 4. This can only be done in Chapter 4, as each level of Seal has a Wisdom requirement; 50-100-150-200. You won't reach 200 Wisdom before going after the Titan pieces, as the missing Stone Tablets are found in the crypts behind the blue barriers.

To further complicate your Wisdom hunt, the skill cannot be trained or boosted with anything other than reading Bookstands for +3, or reading Stone Tablets from your inventory for +4. Once you have 200 Wisdom, talk to Master Ignatius to learn Seal level 4 - 5LP pr level, or 20LP for this achievement.
