Summoning Sciences

Acquisition
Summoning Font in the library in the Apprentice Quarters - Circle Tower.

The quest can also be acquired by finding one of two halves of a torn textbook in the library in the Apprentice Quarters and unlocking Codex Entry: Summoning Sciences:
 * On the table in the first room of the library.
 * On the table in the round central chamber with the stairs up to the next level.

Walkthrough
Several items in the library must be touched in a specific order so that a creature may be summoned. Four exercises are available, the fourth being a "secret' one.

Start
The Warden will find a "Summoning Font" in the library on this floor, clicking on it will start the "quest sequence" and bring up several items The Warden can interact with.'

Note: On PC the all items can be highlighted using the TAB key to make them easier to spot and use.

First Sequence

 * 1) Touch the Summoning Font - This will active the flames.
 * 2) Touch the Tome of Spirit Personages.
 * 3) Touch the Summoning The First.
 * 4) *This will summon a Spirit Hog that will die immediately and drop a Garnet gem.

Second Sequence

 * 1) Touch the Summoning Font.
 * 2) Touch Rodercoms Uncommon Calling.
 * 3) Touch the Statue of Magus Gorvish.
 * 4) Touch the Summoning The Second.
 * 5) *This will summon the Trickster Whim. You will get a Codex for this.

''Note: The Trickster Whim you summon will make an appearance later. The chantry board will update with a quest called Unintended Consequences asking people to find it and stop it.''

Third Sequence

 * 1) Touch the Summoning Font.
 * 2) Touch Elvorn’s Grande Bestiary.
 * 3) Touch the Common Table Carving Spot.

 * 8) *This will summon a Fade Rifter, a Bereskarn, which you must defeat. It will drop a pair of gloves called the Charged Mitts that grant +10% electricity damage.

Fourth and Final Sequence
The Fourth Summoning Sequence is an Easter Egg and is not documented in the Summoning Sciences codex entry. It is a concatenation of the first three sequences (minus the steps involving touching the summoning flames).
 * 1) Touch the Summoning Font.
 * 2) Touch the Tome of Spirit Personages.
 * 3) Touch Rodercoms Uncommon Calling.
 * 4) Touch the Statue of Magus Gorvish..
 * 5) Touch Elvorn's Grande Bestiary.
 * 6) Touch the Common Table Carving Spot.
 * 7) Touch the Spiritorum Etherialis.
 * 8) Touch the Statue of Magus Gorvish.
 * 9) Touch the Novice Phylactery.
 * 10) *Have a character with pickpocket ready. (Note: When you can save, now is a good time!)
 * 11) Touch the Summoning The Fourth.
 * 12) *The fourth summoning will summon a Mage by the name of Arl Foreshadow. You must pickpocket him, and quickly, as he will teleport away shortly afterwards. If you successfully pickpocket him, you will receive Codex Entry: The Notes of Arl Foreshadow.

Rewards
Completing the second sequence also makes it possible to obtain the Chanter's Board quest, Unintended Consequences.

Trivia

 * Arl Foreshadow is a nod to Lord Foreshadow, a character who could be found in the BioWare game Baldur's Gate, spouting mostly inaccurate information about the (at that time) upcoming follow-up game, Neverwinter Nights.
