Breath of Fire: Rod5

Ryu can gain special equipment and items by using the Rod5 to fish in certain places.  These are in the order that I was able to get them.

Well to the Northwest of Tuntar

Head west from Tuntar, then follow the coast around to the north, and you should find it.  Fishing in this well (using the Rod5 and worms as bait) will give you the slab.  The slab has, written on it in ancient writing, the words "Where mystic water lies, the ultimate power sleeps".

Well to the Southwest of Arad

From Arad, head west then south.  Here, you'll find the Dragon Helmet.

Well to the West of Agua

From Romero, head west until you hit the coast.  From there, go south down the coastal side of the mountains and then west to the well.  You'll get the Dragon Sword here.

Duckpond in Spring

After using the Skykey on the machine in Spyre, the waters will thaw in Spring.  Wade through, and fish off the dock to the northwest into the duckpond.  You'll get the Dragon Armour.

Well to the East of Gust

This well is surrounded by mountains, and you need to be able to fly to reach it.   You'll get the Dragon Shield here.
