In an effort to curb people from simultaneously doing all the things and to reward specialization, there is an 'action point' system that is intended to represent how much activity your character can generate in a given week. You receive 100 points a week, up to a maximum of 200, to do with as you will, and certain actions will deduct from it. Additionally, some commands will allow you to invest more points in order to (hopefully) have better results.
Taking an @action costs 50 points.
Assisting someone else's crisis action costs 10 points.
Marking an investigation as active costs 50 points - 5*investigation.
Assisting an investigation costs 10 points.
Asking for support for a task costs 2 points.
Sharing a clue costs an amount based on your social stats, social skills, and investigation skill (100/(social stats + social skills + investigation * 3)).
Adding a clue to an organization costs (20 - 2 * the org's social mod). An org's social mod is listed under @org. Briefing a player shares all clues an org has with the member, and costs (the character's sharing cost / (org's social mod + 4)) + 1.
Crafting an item costs 2 points.
Training someone is free up to your weekly maximum (1 for teaching/animal ken of 0-2, 2 for 3-4, 3 for 5). After that, it costs 100 - 15*skill, where skill is the higher of animal ken or teaching.
