The Underground dungeon in Baldo The Guardian Owls can be found after going down a secret well leading to Rodia Town. Click here for the main quests guide and search for Rodia Town if you need help getting here!
After you climb down the well, head down a short flight of stairs to reach an area with a spiked tentacle. Run past it then head up the stairs and down them to reach the other side of the water. Push the box out of the way then take a left over the wooden bridge. Go up that flight of stairs and drop down past the chain to reach a door on the left.
Head inside and defeat the rats. Next move the wooden box over in front of the flaming pot. Climb up the stairs and grab the pot then jump onto the box.
Walk the pot to the fire to burn the cobwebs holding the chest. Open the chest to receive a Dungeon Key! Exit this room and head across the wooden bridge. Grab the pot and bring it to the boat. Once you step on the boat with the pot it will carry you shortly downstream, and you’ll be stopped by another gate. Drop the pot on the boat then step off to the dock on the left. Follow the walkway along the wall to bring you back to the door. The boat will also return to its previous dock. Head back across the wooden bridge and grab the other pot. Carry it northeast and walk across the bridge to come to a wall with gears and a lit torch.
Stand at the end of the ledge as close to the fire as you can get and throw the pot at the lever across the water. This will release the gate holding the boat next to the above room with the Dungeon Key.
Turn around and grab the pot from behind you. Carry it to the right and throw it at the lever. Quickly run back to the boat and hop in to be taken a bit further down stream. When you’re stopped by another gate, throw the pot at the lever to the right to continue. The boat will dock next to another boat. Exit the boat and follow the path to the right. Go past the door on the left and cross the wooden bridge. Head straight across, passing the large rock next to the stairs leading up. When you come down the stairs on the bridge, continue heading straight to reach the stairs leading up to another bridge. Go up them and head across this bridge. Pick up the pot in the northwest corner of this platform and throw it at the lever to the left to release the boat.
Head back across the bridge then go around the rubble to reach a wooden walkway over the water. Follow it to find a flaming pot.
Carry the pot across the wooden bridge to the north and head straight, crossing 2 wooden bridges. After you pass the second wooden bridge, take the wooden bridge to the left and follow the walkway along the wall to reach cobwebs blocking another boat. Walk into the cobwebs to burn them then step onto the boat to be carried away. When the boat docks again, exit the boat and follow the walkway around until you reach a dead end with a locked door.
Use the key to unlock the door then climb up the ladder to reach Rodia Town!
