Schools as party equivalent for crafting and gathering
Schools would work with rank abilitys. With an additional option when targeting someone in the party : Teach-Learn
Rank 1 Student : learn from 1 Professor (ex)
Rank 20 Stagiere : learn from 1 Stagiere and 1 Educator while teaching 1 Stagiere (ex)
Rank 30 Educator : Learn from 2 educator while teaching 1 Student and 1 Stagiere (ex)
rank 40 Professor : Learn from 4 Stagieres while teaching 5 Students (ex)
then, you build a School, you target a School member with the Learn or Teach menu action to balance party then you gain extra sp from the classe you are learning from. Sp gained vary on rank of your teacher.
You could share your Preserve or other ability with the one(s) you are in relation with. Or you could chain succes synth in a turn based groupe mode. Do skillchain with craft-gath skills. etc.
there you go
