When you enter to the Dungeon for the very first time, the first feature you will see is a really long hallway filled with 20 statues. While you walk down the long hallway you will hear a strange noise. As it turns out that noise is coming from the statues as they are waking up and preparing to attack you. However, they won't actually do anything until you return to the entrance/exit point.
When you reach the end of the hallway an invisible force will block you from entering the Boss lair. Theres really nothing you can do about that, so you have to return to the entrance/exit point only to find that entrance has been blocked by two of the statues. Now it is time to fight the twenty of them.
All the statues are level 38 and they use three main attacks: Electrical Spells, Fire Spells and Physical Attacks. Most of the statues will only actually use one of these, but you must be prepared for all three. There are different tactics against the statues. In my case, I used a series of melee attacks to fight them, but the best strategy is going to be one that suits your particular class and plays on your avatar's strengths.
As soon you defeat them the invisible force will disappear and you will have access to the Archaic Queen chamber. Remember, some of the statues will drop heads in the floor. Pick up those heads as they are the Archaic Sculptures that were mentioned earlier.
