Please correct me in this: as far as I remember, Ahmet is 5th level and Enrico is 1st. Is that correct?
Both are fighters, so I need them to look at this list on the wiki of Fighter Sage Abilities. For the moment, let's pretend that Ahmet and Enrico are just starting out, whatever their level. Both have to choose a field (animal training, leadership, mastery of arms and training) and then a specialty in that field (Judgement, for instance, is in the field of Leadership).
Please take your time reading your options and we'll go from there. I know the exact abilities are not worked out, but you should be able to get some sense of them from the descriptions.
