The best way to get the "Master of ______" trophies is to
go for the "Hardcore" trophy, that is to not upgrade
anything until you get at least 15 points and then upgrade
one skill over and over until it is at the max. Then restart
the game and do it for the other skills. Rate up if this was
helpful.
