BITE let's certain races use their teeth for the obvious reasons. There is some delay when biting, but the damage can be quite good.
Syntax: BITE <victim> In Combat simply type 'BITE'.
As of yet, it's been known for Goblinkind, Gully Dwarves and Minotaurs to bite, other races may have the ability, but no others have been spotted sinking their teeth into opponents yet.
