How do you beat the Stela Chamber's mystery in Pokemon Mystery Dungeon Explorers of Time?

Answer 1

If you are refering to the Aegis Cave mystery, then there is a process you must go through in order to progress to the deeper levels. You will notice that when you defeat Unown in this dungeon, some of them drop a perculiar stone which is marked with their symbol. These symbols can be translated to English letters (and the punctuation marks of ! and ?) and play an important part in the mystery of the cave. You must gather the apporpriate Unown stones which spell out the section of the cave you are in in order to move forward. If you are in the first section of Aegis Cave, then you will need to gather the Unown stones which translate to the letters 'I' 'C' and 'E'. With these in your inventory, place a hand on the notification in the base level and it will clear the path to the next chamber. Proceding to the next chamber will require you to gather the stones marked 'R' 'O' 'C' and 'K'. And lastly, gather the stones marked with 'S' 'T' 'E' 'E' and 'L' to unlock the last chamber and solve the mystery. Once you have navigated through all of the sections of the cave, you can progress in the story. However, if you are defeated in the dungeon or visit Aegis Cave again, you will need to complete the same process as before, and gather all of the Unown stones anew.
