the dyes must be reversed :D
+5dex, +4con, -9str... daggers are skill based and don't need p.atk.
for buffs just the important ones: haste, zerk, g. shield, song of champion, agility... thats my idea
but vs mages you have to boost m.def and mental resistance (sleep, hold...) and ofc the pots(dark, holy, wind, fire...) in gracia
P.S.: and i forgot... use those skills that canceles enemy's target of you... its useful and furstrating for player that you PvP against :D
