Final Fantasy I & II: Dawn of Souls - Flying Fortress - Death Machine
On the 5th floor of the Flying Fortress, there is a rare chance that you may encounter a Death Machine in the wild. Its stats are very high, being capable of overtaking the majority of most bosses in the game. Its physical attacks can strike twice for a large amount of damage, even if you intend to use evasive spells. It also uses a nuclear spell that can strike all of your fighters at once for a fairly large amount of damage. If it’s running low on health, it can sometimes regenerate. No elemental spells will work against Death Machine except for lightning, which just deals neutral damage. Be sure to also have some healing spells on hand as well as a supply of healing items when you’re in danger. The Death Machine pertains to be the toughest wild enemy in the game as it awards a lot of experience and gold, so this is a challenge you cannot afford to lose.
