New plants in new localities may be started with a sprig of mistletoe; the starting process is important, so finding a randomly existing mistletoe plant in the wild will never produce a perfect berry, even if tended. The starting process requires two years, after which the mistletoe will produce 2-8 perfect berries every six weeks. From the first, the mistletoe requires 2 days of tending each month, no more than 20 days apart (else the development process will be extended by a full month or a crop of perfect berries will not be produced).
These berries have various magical qualities that will aid in giving power to shillelaghs and in wand making. At the amateur level of ability, eating a berry in the hour before a battle will give individuals a +1 initiative in their first confrontation. Berries may be consumed throughout a single day to repeat this bonus.
