Tabbin sends you to Karnor's Castle to find three items: a drum, a mandolin, and a performance mask.
The Mask is a small chest drop from trash mobs; sentries and elites hav eboth been known to drop it.
The Mandolin drops from an iksar entertainer in the mess hall, which is at -143, -55, 180 . the entertainer has a five minute respawn.
The Drum can be found in Commander's Quarters inside of a chest. Make sure you have show illusions ON in your Persona window, and be prepared for a fight when you click the chest.
Click the chest at -189, -41, 53 . As soon as you click it, a group of three advisors will spawn and attack you.
Click on the painting at -189, -41, 89 , across the room from the chest.
Click the chest again once you have killed the advisors in order to get the update.
If you have chosen to hide illusions, this step will bug and you will not get the drum from the chest when you click on it the second time. If you get bugged you need to camp and relog to fix it.
Return to Tabbin Juniper. He'll give you The Maiden of Masks, Incomplete. Unfortunately, he has torn out all the pages and used them as IOU's to pay his tabs at different bars across Norrath. Go find all the pages. Examine them like a collection to assemble the book.
Speak to Goldie Sams at Omen's Call in Fens of Nathsar. It turns out Tabbin owes her 185 platinum and 2 copper. Thankfully she lets you pay off the debt by bringing her more fish meat.
Kill 100 Yha-lei for auto-updates. There are plenty of fishmen in the ruins south of Omen's Call.
Note that only one illusionist can get the update from the The Sadistic Bartender at a time.
Due to the rapid elemental effects cast by the bartender, a DPS and healer are strongly recommended.
The Maiden of Masks - Page 4 is found in Kaladim. Click the page in the tavern room before the Queen at -144, 45, -77 . This will spawn a level 83^^^ Golem. Kill it, and click the page again to get the update.
The mob is root/stun/mezzable so is possible to defeat solo.
For the next step, fetch a Cask of Blood Wine from Neriak. The cask is located in the D'Morte Inn in the very back of the New Foreign Quarters at 173, 30, 200 .
Invisibility works against all the guards, but only if you don't have any pets up (including deity and cosmetic pets).
Go to Kelethin in Greater Faydark. Speak to Jysolin Nerala in the tavern near the Granite Hills Acorn lift at 203, 108, 342 . He sends you off to get a cask of Blood Wine, which you have already gathered. Give it to him and receive The Maiden of Masks - Page 5.
The stein must be unmounted, or else Rumdum won't accept it.
After completing this step, you may buy the stein back from the Shady Swashbuckler, so you do not have to permanently lose it.
To obtain The Maiden of Masks - Page 7, hail the bartender at -450, 2, -135 in object:the Laughing Trout] in Rivervale and offer to rescue a damsel in distress and save the world. He settles for a couple of gold though, so collect your page and be on your way.
The Maiden of Masks - Page 8 can be found in The Golden Scepter in Maj'Dul. Be prepared to fight as you hail Ahzeem The Bartermaster at 64, 147, -145 on the bottom floor. After the second dialog choice, 2 groups of 4 83^^ guards spawn and auto-aggro you. After killing the groups speak to the bartender again to receive the page.
You probably won't be able to solo them fast enough, so bring a tank and DPS. You can let the mobs wipe you and then revive inside the Golden Scepter. This way you can take on the mobs one group at a time. If the bartender dies and you finish both encounters fast enough before his corpse despawns, you can still right-click and hail his corpse and get your update.
Warning! Do not have the items in inventory when you first talk to her to get quest. She will take the items and not update the quest journal, so you wont get page. Only obtain the items after receiving the quest.
Have 5-10pp available! These are all T8 house items that cost 10-30g/ea on the broker. You can save money by commissioning a Carpenter to craft them for you.
