When you enter Illusion castle you will see some bones lying around at the start click them and go on, a warning will appear.

You will meet your first boss Crusek Faello, defeat him.

Go on and you will find a wall blocking your way, break it.

You huge crowd of mobs will wait you at the next area, defeat a few and Tartaminos will spawn.

You can go on after you defeated him.

Now the tricky part of the dungeon will follow, you need the right combination for the Altars/Stones which is 2(Altar) - 4(Altar) - 2(Altar) - 3(Stone) - 2(Altar) - 5(Altar) - 1(Stone).

(2)Altar

(1)Stone

A warning message will appear and you have to defeat 2 Orc Commanders.

Go on again and you will see a crystal (Orc Chief's Treasure), click on it and a Boss Mob will spawn.
You can select between 3 different forms (1st destruction/2nd healer/3rd Curse), it depends on what you click.

When you go on a Warning message will appear, now you have to be fast, run to the cave at the right side to kill an Orc scout, otherwise you wont be able to defeat the hidden boss (there is a machine which you attack as well on the left no idea what for it is used).

-Hidden Boss-

If you killed the Orc scout the green wall at the right side will be vanished.

You can defeat now Bigcrup Cuawan to get one more chest.

After it go on again.
On your way you will cross a chest on the ground and a wall is blocking the way, kill the chest once (if you kill it more often the mob amount in the next area will be bigger) and wait till the way will be free (~30 seconds).

You will see 2 cages, click on the right one to spawn the Harpy Boss Sur~.

After you killed it go on and break the crystal wall which is blocking the way.

You will end up in an area full with harpys, if you kill the correct one the Harpy Boss Kierke will spawn (i marked the correct one).

Go on again till a wall is blocking the way, if you break it a warning message will appear and you have to defeat Maga Eyagre.

After you are done with the boss, go down till you meet the Gate Keeper Faellos kill them and the way will be open to the last boss.

The last boss has 2 forms, first one is pretty easy has a spike attack and can go bersek if you take too much time to kill it.
Second one will debuff you with attack/defence decrease.
