 * misc=Many changes and tweaks have been made to this quest since release with Module 4. This raid has been criticized saying it's too easy, caster-soloable, full of loot exploit or relies too much on Air Elementals' unfair knockdown mechanic and such...

Currently as of Module 8, Air Elementals have high saves against Otto's Sphere of Dancing, Finger of Death and such spells, in order to add so-called "challenge" and prevent from becoming population-wide loot run, which once it was.

For puzzle part, it is straight implementation of "Master Mind" game (Wikipedia article). Although using solver programs is very popular among players, it is not too difficult to lean mathematic basics of the game. Try these links if you are interested.
