Hi, I used almost direct translation for the 20 skill nomenclature. Here it goes:
atrocious = kurang ajar
pitiful = menyedihkan
awful = dahsyat
inept = janggal
mediocre = kurang baik
average = sederhana
respectable = agak baik
strong = kuat
proficient = cekap
prominent = terkemuka
prolific = produktif
sensational = menggemparkan
tremendous = terkuat
wondrous = terhebat
marvelous = mengagumkan
prodigious = menghairankan
stupendous = menakjubkan
phenomenal = luar biasa
colossal = terbesar
legendary = legenda
Just for your reference.
Cheers!
