Lineage II/Abyss Walker

Abyss Walker are offensive melee warriors. They use daggers and light armor. They really depend on jumping from behind and backstabbing, before someone starts killing them(they bite the dirt really easy). Their critical power is outstanding, plus the good moving speed and the handy "Ultimate evasion skill" almost makes them impossible to hit. Overall they can kill every class if you have a good tactic and don't face nukers in front of you :)
