I know why the left-handed advantage exists, but it is too good, it is a necessary buy for any Swordsman. and necessary buys are bad. therefore Left-Handed is out, and handedness is a matter of taste.

That puts Ambrogia in a bind, therefore, the new Ambrogia journeyman ability is: NOHP for dagger and main gauche. +5 to Tn to parry.
