Hi, just like the title says I got 2 suggestions for the German translation of the traits:
1. Speed Demon is translated to "Geschwindigkeitsdämon", that sounds like somebody google translated it. Just call "Raser" and every German speaking person knows what you mean.
2. Eagle Eyed is called "Luchsaugen" which translates to lynx eyes, which is a German saying, But "Adleraugen" is also a German saying which literally means Eagle Eyes and since the icon is the picture of an eagle I think it would fit better.
