What should my weapon be if i had a Dodge ninja?
no such thing as a "dodge ninja".. they get 69 job points so just about every build has the dodge skills.. thats like saying what gear for a heal priest?.
Ninjas have over 10 usable builds and they all require different things. The only real cookie cutter builds are magic.. The throw and mele skills havent been figured out well enough by the mass drones who need a pre made char layout yet so that kind of question will go unansered.
For the weapon you want a dagger or a fuuma if you use throw fuuma.
