go to mobs like the Hyungo Ghosts.
get the quest from one of the Guards in Donwhang.
Imbue -> KD -> if kd, stab. if not kd use illusion chain/ strike n' smash -> mob is dead.
dont level up mastery anymore.
when you have collected 200 flags I guess you are level 29, so you have gap 5.
If i'm not mistaken you can get new weapon and shield then.
get them.
of course upgrade all the armor/protector/garment you can.
go to the stable keeper. (don't buy horse man:roll:)
get the earth ghost quest.
kill 500 (!) of them.
after that, deliver the quest and i think you will have you desired amount of SP's.
when you are bord of the quests, just play CTF.
you get a nice amount of xp and sp here and show how blader rocks in pvp
