When meditating to fulfill the catch of Communion 1, multiple elements can be the subject of a single meditation. While this fulfills the catch for multiple versions of Communion 1, there is a downside. The changeling’s meditative connection to each element is weakened by the presence of all the others. The activation roll is penalized by -2 for each element after the first that the changeling meditated upon in the same sitting.
For example, Sam wants to activate Communion 1 for both fire and glass. He meditates for 10 minutes, focusing on both elements. Then, he rolls twice, once to activate Communion (Fire) and once to activate Communion (Glass). Both of these rolls suffer a -2 penalty. If he wanted to do the same thing with fire, glass, and air, all three activation rolls would suffer a -4 penalty.
