Lizardfolk Investigator for Skull and Shackles

[Grod_The_Giant]

I'm joining an ongoing Skull and Shackles game this week, and I was hoping to get some build feedback. I don't know Pathfinder very well, and suspect I might be missing something.

The rest of the party consists of a wizard, rogue, cleric, magus, and bard. I've already talked to the bard, and she's ok with having two social characters in the party. So, meet:
