> a valuable skill

I am really laughing at this one. You got me good. This is either some kind of farming game where I need to "unlock" a valuable skill... ("training" makes me think of NES Super Marios Brothers 3 with the slot machine game after each level), or a skill that I need to add to my LinkedIn profile to check if anyone is reading it. (I recall years ago two guys adding recommendations to each other's profiles with very funny and implausible notes to see if anyone was looking. Does anyone remember that?)
