Mystic Altar

History
The Mystic Altar is situated on the summit of Snowhorn which is the centre of religion and thought for the Minotaurs. Inside are carvings which apparently look similar to demons. But in fact this is about the history of the creation of the Minotaurs. Some adventurers managed to sneak inside and understood this as a sign for demon worship, and so the rumour spread that the Minotaurs are an evil race which has degenerated into demon worship.

It can be said that the Mystic Altar is the essence of the Minotaur culture. The Minotaurs are very proud of their culture and say that the altar is a holy place which outsiders are not allowed to enter under any circumstances. So they guard it extraordinarily fiercely.

But all the rumours about the Minotaurs do somehow mention it: “And now this-and-that item lies hidden in the Mystic Altar and is guarded closely by the dark warriors”. So many adventurers have already died in the Mystic Altar, trying to uncover the secrets of these legends.

Requirements

 * Bosses: 6

Bosses
First, go into the room on your left handside and turn the statue by clicking on it. Then walk back and go down. Head right and go up. Clear mobs, and clear the room. Walk to the end of the room and click on the waterbucket. It will now spawn around 10 ice witches. This is the first boss. Kill the ice witches and some of them drop some loot. They have high magical attack. Let everyone in your party take the water, so you can skip this part the next time.

Go back to the middle, and take the entrance right of the water entrance. Once again clear rooms, and walk to the end. Let someone with the water hit the Brazier. It'll now spawn 0-9 mobs. Kill them and you have a possible chance on loot. They have quite low damage and die easy so nothing to worry about.

If you want quick runs, then skip the last Boss.
