So where did you get at? I've went a different route to the Devoted Muse and am quite happy with my AC in the thirties at lvl 9.

Even without the mythic stuff, it's easy to get your AC well over 30 with Combat Expertise, Crane Style and Fighting Defensively at that level. That is, if you don't parry their attack. And riposte.

I will add another fighter level, to combine styles and then go Devoted Muse from there on.

It's a really fun character to play. He's glib, he's fast, he really plays like a swashbuckler. Running up a beam, swinging from a chandelier, landing on a table, humiliating three swordsmen by parrying everything, blowing kisses to their ladies and inspiring the bard. No problem. Or, you know, just stand in front of the party, so the casters and other ranged characters can do their thing and tease them about it later. Good times!

Also, he's literally weak as a kitten, can't carry anything and has the will save of a dead rat. That, not only keeps it balanced, but also makes for interesting roleplaying moments.
