Two or more Witches can combine their power to move very large objects. Witches working together roll as above, and add their combined Success Levels to determine the Strength of the effect.

This power does not last long. Each turn after the first, another Willpower and Sorcery roll must be made, at a cumulative -2 penalty. So, the second Turn, the roll suffers a -2 penalty; on the fifth Turn, a -8 penalty is incurred. This penalty applies to all further uses of Telekinesis until the Witch gets at least three hours of rest between uses. This ability is good for throwing a few things around, but your character can’t go all Carrie with it.
