Wow, thanks! Shorticus, those are some great options. Chaldira's boons look great for my character, but if I understand correctly, Deific Obedience only grants Evangelist boons? Unless you take Diverse Obedience after, requiring another feat investment.
As an archaeologist bard, I don't get traditional bardic performance but instead get luck bonuses x rounds/day. However, "Archaeologist’s luck is treated as bardic performance for the purposes of feats, abilities, effects, and the like that affect bardic performance." If I'm reading that right, Keerawa, Saving Finale should work as it's an effect, although I'm not sure about Discordant Voice since the description says specifically, "Whenever you are using bardic performance to create a spell-like or supernatural effect," and Archeologist's Luck is extraordinary.
Shorticus, remember, I'm also taking a level of Lore Oracle to get Cha to AC and reflex saves. It doesn't help my initiative, CMD, Dex skills and like however. :P So the Combat Reflexes/Bodyguard idea is not viable, as you mentioned.
I do like the idea of the Harrying Partner/ Shared Training route, plus Cautious Halfling/ Blundering Defense, though you're right, it's an investment and I'd need to commit to one path or another.
I like the idea of a Gunslinger dip, though with my Dex so low and no room for ranged feats, would it be worth it? Or as Heather 540 and Keerawa mentioned, dipping swashbuckler for MWP. Is the Picaroon archetype (for firearm proficiency) a solid choice?
The Mouser sounds fun, though I'm going to stay away from whips. I want to avoid a Halfling Indiana Jane trope. Plus, our previous AP was Strange Aeons where I played a whip wielding Kensai Magus debuffer. Loads of fun and gave our GM a constant headache.
Also, any thoughts on the Pathfinder Chronicler?
Thanks again for all the great suggestions, I appreciate any more you can offer. I'll post a build once I get something concrete worked up.
