Echidna moves without capturing like wazir (one space orthogonally) and captures but cannot otherwise move like lame dabbaba (two spaces orthogonally, if unblocked). What about the ferz (one space diagonal) aspect of the Echidna? We are told: 'The Echidna moves like a King in European Chess' and 'The Echidna captures on the diagonal' -- which makes me think that the Echidna can make either a non-capturing or capturing ferz move. It would be helpful if in the diagram there were a third entry (Y maybe) symbolizing both capture + movement in addition to movement without capturing (m) or capturing without otherwise moving (x).
