So to get hidden u need to max third skill. Yes u need dual wield for all skills wich makes it harder to combine with other classes. Hidden I s one big shot wich has big dmg but shooting takes like 2 secs and cool down....well idk that yet Good sides= this class is fast and can be used while moving so yes....anti rogue class for rangers has appeared. This class has high damage on 2nd skill wich is practically only skill ur going to use in pvp because first skill has too much cool down time and third skill is too weak against other players. Bad sides= two words.....SP DRAINER.....this class drains your sp very fast so be sure to use skills with caution or you run out of sp in no time. I suggest to use gs skills and normal skills with this class to avoid losing sp too much.
