Asura Palace Quest/Spoiler

Method
Go to the Asura Palace in Tiquanda, here. Here you will encounter many Dawnfire Asuri, Midnight Asuri, and Hellspawns, so be careful.

On the very top floor there is a Sealed Door leading to the room of The Flaming Orchid. When trying to open it, you will see the following message: ''You see the images of liches, fire elementals, nightfiends, hydras and destroyers over the doorframe. They're dark and faint.'' In order to be able to access this room, you will first have to kill these five sets of creatures that can only be reached through entrances hidden throughout the tower.

To reach the two Liches, go to the westernmost part of the ground floor and step on Some Cracks. Kill them and go up again. To reach the two Massive Fire Elementals, fall through some cracks in the northeastern most part of the fourth floor. Kill them and go up again. To reach the  four Nightfiends, ascend the western part of the tower as far as you can and then fall through some cracks in front of a chest. Kill them and go up again. To reach the three Hydras, go to the little patch of green on the ground floor and fall into the Pitfall. Kill them and go up again. To reach the two Destroyers, fall through some cracks to the southwest of the green patch on the third floor. Kill them and go up again.

You should now be able to enter the Sealed Door and kill The Flaming Orchid.

In addition, you can find a chest containing three Small Sapphires on the highest floor of the western part of the tower, and a Sarcophagus containing three Small Rubies on the highest floor of the eastern part of the tower.
