Also, it gives you harm/turn evil outsiders and command good outsider abilities. Both of those (and the armor training) are from the purifier archetype. I personally don’t really think the archetype is that great for the build - if you are pure charisma, you are going to be blowing past the max Dex (Cha) limit on your armor even with the armor training. You lose 1 spell/day of each level and don’t get cure/inflict spells automatically. And the real awesomeness (commanding good outsiders) isn’t available until 13th level.
Lunar mystery, though - it’s a good power-build mystery.

I mean there are plenty of armor with high dex cap, there are even a few with no dex cap. So there shouldn't be much to worry on that side.
One of the benefits is that you can make a Strength + Charisma Oracle that deals a lot of damage. Or alternately go with Desna Cha to everything and spend all your ability points into your mental stats and constitution. High Int + High Cha is the way to make Fox Style work which is interesting.
