The exchange of energy via Water is a simple matter that can ultimately lead to the exchange of flesh as well. Within the area of effect of this spell, you may choose a number of willing targets up to your Water Ring. You may switch the positions among those targets as you see fit, exchanging one for another. At the end of the spell, there must be a person in every position that was occupied when the spell began, but who is located where can vary depending upon the number of people affected.
