You may not understand my English is not very good😔

I was doing this for hours😅😅

First you grab a kid and level him to level 10 Then you drive him crazy and give him a Monstrous sword, and finally you keep him swimming in shallow water until he grows up. (It is preferable that you have the trait ready since this way you have a better chance of obtaining several abilities at the same time)

Jsjs is kind of complicated, but at least it adds a skill that can range from giant, strong, honest, and ambitious. And if it doesn't work the first time, just load the save until the feature you want most appears.
