Bridge gone?

The Rano-Connous Bridge indirectly requires an L-Rod. You need to L-Rod near the bridge area on Rano's side to find a Well, use an empty bottle to gather water, then mine rock from Filia and give both of them to the altar on Connous's side of the bridge to make the bridge. (Yes, this required a pet and the purchase of an elf character the first time the bridge was made.) (Note: One of the altars is broken, will not form a bridge, give you the title, etc.)

The Rano-Courcle and the Connous-Courcle bridges can be found very easily with an L-Rod.

The Physis-Courcle bridges don't require L-Rods, there's rocks near the river, hit them to get ore, use the ore to make an ice bridge, that simple.

Only Rano-Connous bridge formation gives the maker a title.
