Orphans: Every player starts out as these, and will be the first mobs for you to grind on. They are found in the Orphanage, and are usually armed only with their fists, but occasionally they wield low level clubs and knives (possibly from player drops). They are weak (around 10hp or less), often sick, and have very low accuracy.
Orphans are not aggressive with the exception of rabid orphans, which can be determined with the job for additional exp..command. Rabid orphans can be killed for 50 credits each from Sister Agnes (go to Agnes and type "-agnes pay"), and satisfies the Orphan Exterminator
