The magüi can gift another creature it deems worthy one of its clay jars that represent the rising springs that give birth to the rivers. The jar can be used as a decanter of endless water for one week, and if the magüi chooses she use this ability to refill a jar that has run dry and extend its power for an additional week. Each day, up to 10 people can drink from the mother's jar and gain the benefit of eating a goodberry; a creature gains no benefit from drinking from the jar more than once in the same day.
