Temple of Water

Head west and cross the bridge. Follow the trail south and you should find the temple there. Once inside, a new party chat will be available. (A Pious Life) Head to the left to find a chest in the southwest corner. Get a Remedy from that chest. Head to the right and inspect the first empty room in the middle. There’s a hidden passage in that room’s southwest corner that will lead you to an off-map chest. Open it to get a Rebuff Locket. There are two more chests to the southeast, containing a Hi-Potion and Phoenix Down. You can inspect the empty rooms here for more dialogues.

Proceed to the north to find two more chests, containing an X-Potion and Ice Charm. Further to the west lies another chest that has an Ether. Save your game and proceed to the Water Altar for a scene. Leave the temple and return to Florem.
