Olympia: The Age of Gods PBEM (Oct 4 2000)
A faction starts with some number of study points. The number of study points available to a faction is shown in the beginning of the turn report. Study points permit a noble to learn a common category skill (Combat, Shipcraft, Construction, Forestry, Mining, Ranger or Trading) without a source of instruction.
When a noble studies one of the above category skills with no other source of instruction available, he uses one study point for each day he studies. For example, a noble in the wilderness with no book who studied Forestry for seven days would use seven study points. Study terminates when the study points run out.
