Lineage II/Coin of Magic-Royal Member

There are two separtate quests that make up the Royal Membership quest; one quest to make you a royal member capable of getting the royal level coins and another that lets you cash in your royal coins (and a few medium grade coins as well) for 60% A grade recipes. = Let's Become a Royal Member! = This quest requires that you have a level 1 membership from your previous coin questing, and are of level 55 or greater. Warehouse Keeper Sorint tells you to get a special Kail coin from the Forsaken Plains. Thankfully, you can cheaply teleport there from the Tower of Aden. Hunt Ancient Gargoyles, Fallen Orcs, Fallen Orc Archers, Fallen Orc Shamans, or Fallen Orc Captains to get Kail's Coin. With that, get yourself to Giran and talk to "Trader Sandra." Can't find her? That's because she's actually called Jeweler Sandra. Buy the coin collecting book for about 11k, if she will sell it to you. The most difficult part of this quest is waiting for the time that Sandra is in "a good mood" as Sorint told you, she will not sell otherwise. Keep coming back. I've bought a book once and a person not 30 seconds later said the quest book was no longer there. Remember that although someone can buy as many books as they want, the items cannot be transfered to another character, so there is no way to buy a few for your closest friends. Once you have the book, go back to Warehouse Keeper Sorint and complete your quest.

About 45 Ancient Gargoyles kills will yeild Kail coin, and Sandr is always in a good mood every 4 hours
