Firstly, you should create a village with adamantine. This will get the villages good amor. When they are armored enough, spawn a dragon. The villager that kills it will be the chosen one. Add him to your favorites.
Then add the coffee and bubble shield rain perks. Don't use the trait editor at any point of getting the achievement.
Spawn an evil mage close to the guy. Make sure no one could steal the kill. The villager should kill the mage.
After that, create a small village. When they have a king, take him with the magnet to your villager. Give him madness. He will kill the king.
Lastly, spawn a lot of grasshoppers with madness next to him. By killing them he will level up.
Another way of doing this achievement is by downloading a map that has people with all traits.
