Crafting steps

1. A craft takes Steps steps, one every Interval. Each step needs the full Item cost and Currency cost on hand, or crafting stops.
2. While more than one step remains, Step Skipping Chance completes two steps at once.
3. After the last step the ingredients are spent, unless Input Preservation Chance keeps them.
4. The craft then pays each Products entry whose chance succeeds, in ascending chance, each doubled with Output Doubling Chance, and XP once per craft.

Game messages

skill StoppedLack of resources available.

A finished craft leaves too little of its Item cost or Currency cost for the next one, and the skill stops. Cooking, Firemaking and Herblore stop with the same message.

Guild points

1. Each completed task adds its category's base points to its skill's guild; a task that stops being complete takes them back.
2. A skill's total points are the base points of every task it lists. A rank is reached at ceil(total × the rank's point percent) points.

Prayer XP

1. While any prayer is active, each of your hits that deals damage pays XP from Base experience, with that hit's damage and the summed base cost of the active prayers.
