There is a magical tree whose leaves can be harvested in the autumn. The leaves must be harvested as they fall from the tree. If they touch the ground they are worthless. The person attempting to harvest the leaves must make a stress die roll to determine the quantity harvested from the tree. Each botch (5 botch dice rolled) gives the harvester a -1 penalty to harvesting from the tree in the future and these penalties are cumulative. The penalty goes away at one per year. Only one person may attempt to harvest this source per year, otherwise the leaves yield no vis.
