How to kill Zaken?

There are a lot of candles around, when you hit them, they turn to blue or red and summon the minions (and Zaken if you are lucky) in the room.
The blue candle means Zaken is nearby, in one of the rooms around the candle.
When you find all the 4 blue candles, Zaken will appear in the room, surrounded by candles.
Be careful, adventurer, more candles you light, the stronger Zaken you have to fight!

There is a trick how to find Zaken.
Daytime Zaken and the minions are invisible until you start lighting the candles.
So whenever you enter, send someone with AoE attack to sweep the rooms, and use AoE spell in the middle of every room.
Zaken is invisible, but still exists, so after some time the scout will hit Zaken with the AoE skill.
Then you only have to light the 4 surrounding candles and kill it in few mins.
Don't forget to drop some adena, or mark the checked rooms after the scout.
