Welcome to Pet Forest. In Pet Forest barbarian's are basically the meat shield. High HP,moderate physical defense, low magical defense, and low damage.Here are some useful Barbarians Guides for Perfect World Players. Hopefully the article can help you. I believe you will learn something from it.
Levels 1-19:
At earlier levels playing a WB is a cake walk. We have high HP to start with and if you go with the build i mentioned above you will have around 1k HP by level 15. Not to mention 99.9% of the mobs you'll be facing at this level will be physical and you wont have any magical mobs until at least level 20.
You will only have one skill to start with which is Beast Lords Whomp(Bestial Hammer). Use this to quest and grind your way to level 3. By which time you can go into vanish and can learn Garrote(Strangle) learn it. It's a good soloing skill at lower levels. I highly suggest that you don't waste any SP on upgrading BH(Yes,bestial hammer. Try and keep up with the acronyms). This skill will become obsolete at higher levels when you'll be needing all the SP you can get to get a skill which is actually useful. Once you get to level 9 go to your skill master and learn your transformation skill this will transform you into a tiger which will increase your movement speed,and physical defense, Pet Forest Gold while decreasing your attack. Always level this skill as soon as you can even though it only goes to level 3.
Continue on your way to level 19 while putting only enough points into strength and dexterity for your dual axes and heavy armor and everything else into constitution. Once you get to level 19 you'll get your iron blood tablet from the vanish elder. Make sure you do this quest it's your first FB and you'll get an awesome blue Poleaxe which you'll likely use until level 35 or so. You can probably find lots of people willing to help you and earn some rep for themselves.
