Find Familiar: Scratch	Summon the best boy. Scratch's keen nose can discover many things hidden around the world.	Leave Scratch with your scent so he joins your camp, then later when he offers you a ball, throw it to play fetch with him.
Find Familiar: Shovel	Summon Shovel, the Cheeky Quasit. Pact of the Chain unnecessary.	Find the unique Scroll of Summon Quasit in one of the coffins of the hidden area in the Apothecary's Cellar beneath the Blighted Village.

Awakened	You can use all of your Illithid Powers as a Bonus Action	Make the Zaith'isk in the infirmary of Crèche Y'llek explode and succeed at all three saving throws. The saves are significantly easier if you are in the device rather than Lae'zel. The person that gets the buff is always the player character.	Failing any of the saving throws for the Zaith'isk inflicts permanent, stacking penalties to your Ability Scores: 1 failed save: -2 Constitution 2+ failed saves: -2 Intelligence

Bless	Gain a +1d4 bonus to Attack rolls and Saving throws.	Pay Boney in the Circus of the Last Days 5000 gold to construct a statue of yourself.	Can only construct a statue for a single character. The effect begins once you long rest.
Monk's Hideous Laughter	Gain casting of Tasha's Hideous Laughter per long rest	Carry the Sentient Amulet from Grymforge to a casket under the Open Hand Temple in Wyrm's Crossing, completing Help the Cursed Monk. Must choose to accept the curse yourself.	Possible wisdom loss if you fail Constitution/Wisdom saves. The sentient amulet seems to lose all of its abilities after the quest completion.
The Tharchiate Codex: Blessing	Once per long rest, gain temporary hit points	Read The Tharchiate Codex (found at the end of the Vault puzzle in Ramazith's Tower)	Remains active if The Tharchiate Codex is also used to obtain Danse Macabre
Danse Macabre	Create 4 ghouls that fight alongside you	Read The Tharchiate Codex (found at the end of the Vault puzzle in Ramazith's Tower), then read the last page of the Necromancy of Thay (from Act 1) and pass a 20 Wisdom Saving Throw	Comes with a curse that lowers Constitution by 5, but can be removed with the Remove Curse spell while keeping Danse Macabre
Mirror of Loss	Gain +2 to an Ability Score of your choice (and optionally +1 to Charisma)	Offer a prayer (DC 25 Religion Check) to the Mirror of Loss in the House of Grief, then sacrifice one of the following: Constitution, Wisdom, Charisma, or your knowledge of the Necromancy of Thay. You'll receive the option to choose a +2 bonus to any ability. If you sacrificed an ability, you'll receive the Stolen Vigour curse (-2 to that Ability). This can be cured via  Remove Curse. Occasionally, when sacrificing an ability to the mirror, you may receive the Patriar's Memory buff (+1 CHA). If this happens, interact with the mirror again, sacrifice your knowledge of Necromancy of Thay, and choose an ability to receive a +2 bonus. After both interactions, the mirror is sated. Cast  Remove Curse and you are left with +1 to Charisma and +2 to an ability of your choice. (See notes!)	Can be raised above 20 (up to 24) If no prayer is offered prior to sacrificing memories, no bonus is received. As of Hotfix #4, all bonuses from the Necromancy of Thay are retained when you sacrifice its knowledge, along with the Ability Score increase - this is likely a bug. As of Hotfix #4, it is unclear whether the Patriar's Memory buff is a bug, as it doesn't trigger every time. This may require several save-and-load attempts to attain. It is also unclear whether there is a way to gain a +1 bonus to ability scores other than Charisma - possibly a class-specific Arcana check? [Needs Verification]
Unstable Blood	Your blood is now highly flammable and will explode on contact with fire	Give your blood to Araj Oblodra in Moonrise Towers in Act 2, then meet her again east of The Blushing Mermaid in Act 3 and help her again. She will give you a potion that grants this feature once drunk.
