anyone got idea where the artist that the black cat looking for?
Auguste is in many different places.
1. Boss room in the Cathedral.
2. Left side of the "Pruning Officer of Garden".
3. Statue in Uramvana city.
4. Left cliff-face of the "Groan Valley".
Finally, at the end of the game there is a hidden, optional boss in the dungeon of the Castle of the Midnight Sun, "Cruz's Jail", you must go through the library to the left of the castle and find a bookcase that reveals a passage (the bookcase is next to a scratch-mark message), head through that dungeon and you should find a final door that will only open if you have met Auguste the previous four times.
