In the SR5 rulebook, there are two sidebars on pages 279 and 280, respectively, dealing with the hermetic tradition and the shamanic tradition. I understand the difference between the two in regards to the differing attributes used for drain. But I don't get what it means for the two traditions to tie the 5 spell types to different "elements" or spirit types. For example, what does it mean, in game or in fluff, that a hermetic tradition has combat connected with fire and shamanic has combat connected to beasts? I get that shamans can't summon fire and her ethics can't summon beasts, but beyond that, what is the point of the connections?
Thanks,
