Star Ocean: Till The End Of Time

The Aquatic Gardens of Surferio is an optional dungeon that is very low leveled, you don't need to wait until the post game to play through it and I would actually suggest doing it after you complete the Shrine of Kaddan for the first time. To get to the dungeon, you must go to the Irisa Fields (North of Peterny) and go to the path that leads into the Northwest section. From there go West until you reach a save point, next to the save point is a flight of stairs that lead to the dungeon. Use this FAQ to guide your way through the dungeon ("CTRL+F" to find this dungeon) and its puzzles, once you reach the end of the dungeon you will face the Sculpture Lord.

Sculpture Lord's Level: 45
Recommended Level: Early to Mid 30's

Sculpture Lord at this point in the game is essentially a pushover. The only real challenge will come from the rock enemies that are next to him: so defeat them first. Once they're defeated, your party should be able to overwhelm Sculpture Lord with ease. Once he's defeated, you'll have access to the Paracelsus Table which you need to complete for Spoiled For Choice. Once you defeat Sculpture Lord, the trophy will unlock.
