'''The Necromancy of Thay'''

There are secrets of life and death known only to the Red Wizards. Committing such secrets to parchment is a risk they are loath to take, lest the unworthy gaze upon them. Who better, then, to guard their secrets, than the spirits of the jealous dead themselves? 

The look upon the Necromancy of Thay is to risk madness at the hands of its spirits. But the wise traveller, who can tread the line between life and death, will find knowledge witnessed by precious few mortals...

* [[The Tharchiate Codex]] is stored in the [[Sorcerous Vault]] beneath [[Sorcerous Sundries]] in the [[Lower City]]. You can reach the vault in two different ways:
** By interacting with the Clasped Book in the bookshelf of [[Tolna Tome-Monger]]'s office upstairs and going through the portal, or
** By using the Weave Button labelled 'Vault' on the middle level of [[Ramazith's Tower]].
* Within the vault, the Codex is located in the Elminster section. To unlock the Elminster door, you must first find the lever at the end of the Silverhand section by opening doors in this order: Silverhand, Evocation, Wish. Alternatively, you may unlock the Elminster door using the [[Knock]] spell.
| notes = * Reading this book has the following effects:
** Curses you with {{Cond|Tharchiate Withering}} (your Constitution score is lowered by 5). This can be cured with {{SAI|Remove Curse}} or {{SAI|Greater Restoration}}.
** Once the curse has been cured, you receive {{SAI|The Tharchiate Codex: Blessing}} passive feature, which grants you {{Cond|Tharchiate Vigour}} (20 [[Hit_Points#Temporary_Hit_Points|Temporary Hit Points]]) immediately and also once after every [[Long Rest]]. Characters with this condition will lose it immediately after using Withers' [[Class Change]] service, but the condition returns after the next long rest.
* After reading [[The Tharchiate Codex]], you can re-read {{story|Necromancy of Thay}} and pass a DC 20 Wisdom saving throw to gain the permanent ability to summon 4 ghouls via the {{SAI|Danse Macabre}} spell once per [[Long Rest]].
