The quest of the suspicious rat.

Answer from: Drew
I found the mana crystal in the secret passage near de lauren castle. it is a very rare drop from one of the monsters tehre. cant exactly remember which one though. all i know is that it is a monster drop in one of the areas (sanctuary, secret passage, castle underground) at the end of the game

Mana crystals and trancendence flower they drop on almost every kind of monster especially those of higher levels both are composition materials, for supreme elixir.. i had a hard time finishing this quest to so i decided skip it & go on with the game ... and as i did i found both composition materials ... and went back to the suspicious rat to complete it... don't worry you'll find both composition materials as you go on the game .. actually you might even find more than you need, supreme elixir is helpful in increasing stats permanently. the best advice i can give is just skip this quest go on with the game and surely you'll find both composition materials.. and after that there will be two more quests from the suspicious rat, but this quest will be no longer difficult because he'll provide you with the dagger that you'll need or maybe everything you need for you to use on the fusion machine.. i guess i wrote too much
