New n00b with question

[robbo79]

First let me say hi to everybody and thanks to the ones that already helped me in game.

Now about the question, subject is crafting.
Yesterday i was working on my big plan A: "Conquer the world in 3 easy steps" when i realized i had my priorities wrong, so i switched to plan B "Get yourself dressed". Given i was the richest being among yubos i bought all quality 50 raw materials to craft a magic amplifier wich turned out to be quality 10. So here comes the question: crafted quality is determined solely by raw materials employed in the process? Or you have to improve your skills, like "craft quality 20 yubos underwear"?

Thanks in advance for the answers.
