The Barrier

Treasure Hunter

Why are we here? Well, listen up. I'm not skipping out on details! - Merlin


  1. Talk to Merlin. If he is not visible inside the barrier, try changing channels. You will enter the Shadow Mission, "Cessair's Heart".
    • You will role-play as Cessair's Heart.
      • Reduce Merlin's HP to below 50%, then lure him to the red circle on the lobby floor.
      • Cessairs will constantly spawn to aid you.
  2. Talk to Merlin again.
    • You will enter the Shadow Mission, "Secrets Unfolding".
      • You will role-play as the Treasure Hunter.
      • Investigate the writing on the 4 stone tablets.
      • Head back to Pinky. Choose 'Solve Puzzle'. You will have to solve a sliding puzzle.
        • The puzzle consist of 8 blank-pieces and 1 empty space.
        • Clicking on any piece will move it to an empty space. Moving the pieces will reveal a pattern; clicking on the piece again will make the pattern disappear.
        • Some pieces will eventually reveal the correct placement of the piece. Remember the correct placement.
          • The entire puzzle appears blank in all 9 spots, but the middle piece is currently empty and will not be in the final solution. The 8 surrounding pieces are jumbled. When a piece is moved into it's correct position it will reveal a line pattern, Moving the piece out of position will make the pattern disappear again. Therefore the line patterns don't mean anything, all you need to do is move pieces until you can see they are in correct position and remember where they belong if you move them out.
          • Once you have managed to put 3 puzzle pieces into correct position, getting the remaining pieces into their correct position becomes difficult to do without displacing the solved pieces out of the way temporarily. You will have to develop 3x3 sliding puzzle interchanging technique. If you are not good at sliding puzzles, think about moving the empty hole in the shape of an 8 and notice how that moves a piece that was on one half of the 8 into the other half of the 8. You can do this puzzle if you stay calm and develop technique around rotating pieces in 2x2 circles and a 2x3 8-shapes.
          • After some length of time, the puzzle will become easier by revealing the patterns of the pieces and it will allow you to move pieces diagonally as an easy method of getting pieces into difficult positions. It is still possible to complete the puzzle when this happens.
      • Talk to Pinky. A cutscene will occur.
  3. Talk to Ruairi outside the barrier. If he is not visible inside the barrier, try changing channels.
    • A cutscene will occur. After, you will be teleported outside of the barrier.
  4. Complete the quest. [12,000 EXP, 10,000 Gold]
