Burnt Offerings

You provide an offering to the Wyrd (Weave) in the hopes of receiving a small guidance.  You must set aside a day's worth of food or rations to be burnt away to ash as you meditate on the dancing smoke and embers.  As long as you are not interrupted, you gain a small pittance from the Wyrd and may reroll any one roll for the next 24 hours.
