Appendix D: Mist Levels
II: Levels 11-20
Remember, groups that join together must attempt their feat within one hour of the first two PCs joining together or they will lose all collective benefits. This includes collected mist points, which will dissipate back into the greater mists and be gone for good. I.e. Use expend to attempt the feat within an hour of first using join or you'll lose everything.

A staff presence of some sort is necessary before attempting to perform any mist handling feat of level 11 or above.
