What do you get for using Iron Keys?
Any good JRPG will reward players who are eager to explore every corner of the world. While likable characters and a strong story are important to the genre, things would be different if there weren't chests filled with treasures for players to discover. This is especially true of JRPGs Fantasian Neo Dimension. This game has a lot in common with classic JRPGs from the 90s that have stood the test of time, and that includes chests filled with useful items everywhere.
As you progress through the game, you'll come across chests covered in chains. The only way to open them is to find the Iron Keys, and that's how you can get them.

How to get Iron Keys in Fantasian Neo Dimension
Iron keys can be found in a number of ways. First, Iron Keys are periodically a reward for completing side quests such as Sick Mother. Also, Iron Keys can drop at the end of a battle. Not only that, but there is a special enemy known as the Key Orbling that is guaranteed to drop an Iron Key. They are hard to miss in battle as they are large blobs with wings that carry a large version of the Iron Wrench.
One of the best ways to farm Iron Keys is to keep a bunch of enemies with Dimengeon while roaming the map where you can be attacked (aim for around 10-20 depending on how well equipped your party is). Then, once your party is ready, activate the Dimengeon battle and take them all out. There is an element of RNG, but the monsters are saved, the more likely one of them will become a Key Orbling. With all the bonuses in the Dimengeon battle, this device is also an effective method of leveling up.
