I started going through Cythera, and got myself hung up on a rules question. Mithral brings armor down a category for movement 'and other restrictions,' but mithral also requires proficiency at its normal level. Cythera clearly has proficiency from fighter levels, but my question is: is the bard ability to avoid spell failure tied to his specific armor proficiency? Bard training is specialized to learn to work armor into somatic components; fighter training wouldn't really be bothered by it. i.e. is the spell failure lifted by the first part of mithril or kept because of the second?
It's an honest question, as I've never encountered this particular combo before.
