1F
Once inside the temple, a party chat will be avalailable. (Vestal and Acolytes) Loot the chest to the left to get a Wind Charm. Head to the east and inspect the messy room if you want for an optional dialogue. Head to the right and go downstairs.
B1
Head to the west and open the chest along the way to get a Remedy. Follow the straightforward path to the north and open the chest to the northwest to get a Hi-Potion. Loot the chest in the middle of the room to get a Turbo Ether. Once done, make your way to the southeast corner of the floor to find the stairs going up.
1F
Head north and inspect the messed up room to the right. Continue along the path and go upstairs to the northeast.
2F
Go down south then west. Don't forget to open the chest in the southwest corner to get an Ether. Make your way to the northwest corner to find a Mythril Rod from the chest. There's a masked NPC in the room beside the chest but he'll turn you away for now because you're "lacking qualifications“. Use the stairs in the middle north of the room to go back to the first floor.
1F
Follow the path and the party will have another short conversation as you pass by the ruined room. Pull the lever nearby to open the door leading to the exit, then head to the west to find the last chest in the floor containing a Mythril Dagger. Talk to the adventurer near the exit and save your game. Go through the door to reach the crystal.
Altar of Wind
Head to the altar and examine it to continue with the story. Leave the Altar and inspect the room to the east for a short scene. Once done, leave the temple and make your way to Yulyana Woods. You can stop over at Ancheim to rest at the inn or grind to earn some money for upgrading your party's equipment.
