Reflex or Defensive Sense
*For the two builds for FBs itís recommended to use Reflex but if your a pvp oriented type go with defensive sense*
FBs at lower levels and skill rank are pretty much weak. But once a FB reach A.Master rank, thatís where it gets stronger.
Get to lvl40+ asap to use adept items. Get the +3/4Skill Exp ones(adept aramid battleset).
Then go punching, it might be boring but itís worth it. Punch all the way to Dual Master, stop your Magic at Master 33/96 to get all your buffs(Lightning blade, Earth Guard, Aqua Vitality and Wind Movement) at lvl20 max. Then go to the Port Lux instructor and get Force Change Magic to Sword, with this you can gain more and faster only for SWORD. Go get a noobie sword(in order to use your buffs to support you while skill grinding namely Earth Guard, Aqua vitality and Wind Movement), then go punching(normal attack).
For leveling magic, do the same just replace Force Change magic to sword with Sword to Magic.
If you got premium service, it would be better and buy a board if you can afford it becuause it helps you in skill grinding (+hp,+def, +4Skill Exp , regens 2 hp and mp per two secs)
Leveling is easy when you have high skill rank and have strong skills at your disposal. XD
You can have higher hp than the others at your level and you can own a lot of people in PvP. =P
Do some quests in between so that you can earn some money to buy those skills.
Concerning on weapons, you can use katanas or blades it depends on you which you like better. You can also use Crystals rather than orbs because it has more attack than orbs *follow the Force Shielder stats*
Get as many items with sword amp as you canÖ. 2 is quite enough or 3 if you wanna be uber in pvp O.oÖ Also get critÖ
