A mage who whips up a serious storm-front may want some protection. And so, it’s often a good idea to forge a “storm cocoon” around yourself if you’ve got tempests on your mind.

A traditional cocoon employs Forces 3/ Entropy 2/ Prime 2: Forces to shield the mage with elemental power; Entropy to adjust the probability of harm from random elements (falling roofs, flying debris, arcing electricity, and so forth); and Prime to fuel that shield and keep it in place while the mage concentrates on other things.

Generally, a five-success cocoon protects the mage and/ or her companions within a roughly 10’ circle, for the duration of the storm. Additional successes are required to protect larger areas – say, one additional success for every additional 10’ of protected space.

Unless the cocoon forms an obvious bubble of protection (like a glowing force-field or an air-filled bubble underwater), the cocoon remains coincidental. Under certain circumstances (such as a technician setting up a hypertech protection field), it may be coincidental even when its effects are obvious to the average observer.
