Stats: Pure Agi(use twilight rings and stat potions if you need to equip something)
Essential skills: Tai Chi / Rabbit's Movement / Brave Heart / Boxing / Eagle eye / Weapon master / Abyssal fury / Pipemanship / Dragon Striker / Asura Strike.
All those skills are essential must have skills! master those before you master anything else..for eagle eye and weapon master lvl those both to atleast 14. for dstriker and asura lv1 to 10 whatever you prefer
Automatic Skills: Good automatic skills are Sun Spirit(lv20-21) Moon Spirit(lv10-11) or for support do Battle aura(lv20) some prefer Precision strike(lv10-20)
Active skills: Anything creative you want but Asura strike and Dragon Striker will be your main means of attacking. You could try a hybrid healer fist user and use Silent Rain lv20 but I havent experimented to heal your team but thats not really barehands role in battle.
With the rest of your SP just do what compliments your playstyle, I prefer Iron Body lv20 / Power of sun lv10 / Panthers Speed lv10 / lightning reflexes lv10
Gear: Lv1-30 anything good you can find jus try to better yourself til lv30
Lv30: The most common and best is Full Avenger hands down shield anything good that you can use
Lv45: Ares is good for dodge if you need it and ares red shield
Lv55: You can use full Moon Secret but I think it benefits you more if you use this set up : MS Head, Ire of Abyss, Ping Ba Legs, MS Boots, MS Gloves, MS Coat, Ares Red Shield, or Medusa shield for PvP, Evil Cloak or Thor Cloak. For a mount I would use Nine Dragon General Athlon for the physi hit boost and agi 15% Rings use Agi Strengthen Rings and earring or Azrael ring earring and necklace, for necklace either use hero mithril necklace orAzrael Necklace.
Gemming: Use atleast 3 of items for pyhsi hit gems and rest agi gems or maybe one hp or mp.
Pets: Use epic fairy, Azrael Pet, Flash Element, Bear dont be afraid to experiment with your pet and add skills. The most important skills you want on your pet is protect or shield.
