I'm new to ts2, so I'm not sure its right or not. Feel free to leave your comments here.

----------Character Stat----------

here is three kinds of stat bulding:

1st, leveling up: 3 Str 2 Dex or 4 Str 1 Dex

this type can help you to level up much easier. You can kill monsters fast, cuz you have more attack. But if you want to PK, never try this way! Low HP will lead you to death quickly.

2nd, level up and pk: 3 Str 1 Dex 1 Vit or 2 Str 1 Dex 2 Vit (balance)

This is a balance way. U can level up easily, and survive better while pking. But you won't level up fast neither win the PK. so, I wouldn't recommend you to use this way.

3rd, for PK: 4 Str 1 Vit or 100% Str

If you are rich inGame, do it! You need much money to level up, and grinding slowly. but you have the greatest damage especially 100% Str!

----------Skills---------- (http://12sky2.mmosite.com/us/skills/skill0202.shtml)

1st, leveling up:

Cold Hearted Cut: useless.
Freezing Tangent: not recommended. spend 5 points on it at the most. (you won't use it when you reach higher level)
