What's going on in the watery room with the stone columns that sink?
  • 1 of 6: Stand on them and sink them.
  • 2 of 6: But they just rise back up.
  • 3 of 6: Try standing or moving around on the biggest one.
  • 4 of 6: Its middle should soon sink down a few inches, revealing a hidden button on the middle of the west side.
  • 5 of 6: Use that button to open a secret door in the north wall.
  • 6 of 6: Inside the secret room are two treasure chests, one of which is a black chest with a Lock Difficulty of 24 (needs a level 8 master or better Disarm Trap skill).
