Special Purviews /do/ still require relics to use. The pantheon-specific purviews are the only exception to the 'need a relic' rule, and they can't be used by any other pantheon.

The Animal purview isn't restricted to your parent's(or the granting god's) favored animal. It's just there as an example.

Thanks, Devarash!
