Witches exist at all levels of society, including the top echelons. These individuals summon the orgone within themselves to perform various feats of magic through invocations. Magic is done within an incantation circle, surrounded by the various objects and materials needed for the spell. All witches are born with a set amount of orgone, or "power level". There are certain spells which require more orgone than a witch possesses. While the rare and powerful witch would be able to pull it off, most others would have to find some other way to pull it off. In this case, they would combine their power with other witches to make up for the amount that they don't have. Say a certain spell cost 500 orgone and a witch only has 100 to spare. They would need 4 partners to participate, with 100 orgone each, or some combination that adds up to 500. For spells to work, all participants must be linked to each other and perform the invocations in sync. 

However, there are a number of problems with this. Two witches performing magic in close proximity to each other cause interference to each others magical "field". This disrupts the spell, causing it to have reduced effect or even misfire, harming their compatriots or even themselves. Additionally the witches have to pour more orgone into each spell to overcome the disturbance. This in turn causes more interference, etc. It also means the witch gets exhausted quicker. If combining power levels makes performing magic more difficult, it defeats the purpose of doing it in the first place.

For this type of magic to be successful, these hurdles must be overcome. How can this be made possible?
