A woman in the town of Leedo gave me a quest involving searching through the Lizardo Dungeon and finding 4 of an item called Lian Clamp.
I've found three of the four, and though I've scoured the rest (I think) of the dungeon, I haven't been able to find the fourth.
These are the first two items, located in the top-right of the dungeon's second floor.
This is the third item, located in the lower left of the dungeon's second floor.
Is there a hidden doorway or something that I'm missing? Where is the last one?
