My Empiricist need some advices

[Shaffi]

Hi, I'm currently playing my first pathfinder campaign (Rise of the runelords) as a Empiricist. We got the option to reroll our stats, the class or even the character in case we aren't happy with our decision.

I really love the concept of the investigator class, but my old character had some problems especially in battles. So I decide I would just reroll my feats and talents.

At the moment we reached level 3 and this is the build for the future.

Feats & Talents

I will be using daggers, I thought about kukris but I wont be able to use the inspired weapon enchant.

I would really appreciate some advices.

Thanks a lot

Take an Inspired longspear and combat reflexes instead of two-weapon fighting. This will help your action economy massively and saves you some feats. I really would not go TWF with an investigator, it's really hard to pull off well, especially since you can use extracts of alter self to shape into forms that give you more natural attacks than TWF can ever give you.
