Way of the Necromancer

Way of the Necromancer is a side quest in Dragon Age: Inquisition. It is one of three potential quests which a mage Inquisitor can complete in order to obtain a Specialisation.

Acquisition
This quest is not available until after From the Ashes has been completed. Go to the War Table in Skyhold, and a quest for the Inquisitor to choose a Specialisation will be available. Three potential trainers, one for each specialisation, will arrive at Skyhold to teach a mage Inquisitor a specialisation (unlike in previous games, only one can be learned). To access this quest, talk to the Necromancer trainer, Viuus Anaxas.

Walkthrough
The following materials must be required in order to finish this quest:
 * Writings on necromancer magic: this can be obtained from either Dorian or the book merchant in Val Royeaux.
 * Da3-091.jpg Nevarran skulls: These can all be found in The Storm Coast. When an undead is killed in these areas, they have a chance of dropping a skull. It may take multiple visits to an area in order for them to drop one.
 * 10 bloodstones: These can be primarily found in the Emerald Graves and Emprise du Lion, though you can run the Emprise du Lion Resources mission with Cullen if you don't want to collect them yourself.
 * Materials for a jeweled skull.

Rewards
Completing this quest will allow you to obtain the Necromancer Specialisation.

Other

 * All three specialisation quests can be done at once, however, only one can be completed.
