Thanks for the advice! The reason I didn't choose Investigator is that I don't have the Advanced Class Guide, so I don't know the stats. Also, what books are the Breadth of Experience, Scholar, and Focused Shot feats from?
Edit: Just checked out Investigator, and it turns out that they can make all Knowledge checks untrained at 3rd level, while the bard can do it at first, so that's a problem
Edit: Nvm, figured my last question out, and I found the Investigator stats
Bonus: Breadth of Experience lets you make knowledge checks untrained, so you might be able to drop the bard aspect altogether: Maybe go with Alchemist or Wizard?
