too expensive in my opinion... and only 50% chance for a level increase. if you wanna level up, i have like 3 or 4 sets of skilled hn for trade. way cheaper
HN skilled don;t do anything for SR and Up, they only give a 1% each, so if you used 10 it only gives like 9% chance. To get a SR skill above lvl 3 or 4 you need DQ to do it. and they are going for about 50 hp right now so good luck
