Doing the Quests
Located in the right top corner of Meridell, Illusen will ask you if you like to accept her request. Her requested items are cheap at first, but expensive as the levels rise up. The Shop Wizard can be used unlike the main Faerie Quest of Faerieland. Highly priced items may lead you to go through the Trading Post or Auction House, if they can't be found by either of the three, the neoboards might help.
No-trade Neohome furniture is a possible request and can be found at the Nehome Neostore.
Now Jhudora's quests is a lot rewarding than the earth faerie and all, but Illusen is quiet cheaper going on with her quest and reward the great Leaf Shield and Illusens Staff. If you do a Jhudora's quest, you won't be able to do one of Illusen's quest for 12 hours and on Jhudora's day (February 4th), you cannot do one of Illusen's quest.
As a prize, you will receive one of these prizes depending on level:
Avatars that can be obtained from Illusen's quest:
Complete Illusen's 20th quest.
Complete one of Illusen's quest on March 17th.
