Final Fantasy I Walkthrough

6. The Marsh Cave is Endless

Travel west from Elfheim to the coast, then head south and you’ll find yourself in a marshy area. At the very south of that area is a hole, the Marsh Cave.

This dungeon is pretty big, and the enemies love to poison you. It’s recommended to bring along 99 Potions and at least 50 Antidotes. It may seem like a lot, but you’ll likely use most of them, especially if you heal after every battle, which is important here.

You start off in a room with two paths. Assuming you want to get all the treasures, you’ll want to take the north path first. After travelling down some stairs, you’ll be in a large room with many doors. There are two treasures here, 620 gil and a Dagger. After you’ve cleaned that out, return to the entrance and take the south path to a ladder down to another room. In this room, you can find a Broadsword which isn’t as good as the Mythril Sword you can buy in Elfheim. You can also find 680 more gil. In the southeast area of this room, you’ll find stairs down to another room. This final room is gigantic, and there are many small rooms with treasure chests. You’ll find many rooms locked, again, with the Mystic Key, two chests with gil totalling 680, a Steel Plate, a Cottage, a Copper Armlet, and finally, a treasure chest surrounded by statues that will begin an encounter with some Piscodemon enemies as you approach it.

The Piscodemons can do a lot of damage a round, so finish them quickly. Your Warriors, Monks, and Thieves should be attacking. Your White Mages can attack with their hammers unless you need healing, which is their main priority. Your Black Mages and Red Mages should be casting Bolt2. It shouldn’t be too tough, especially if you’re at level 10 or above. After the battle’s over, open the chest to get the Crown that you came for, finish looting, and leave the cave.
