According to the core rulebook, druids are proficient with clubs, daggers, darts, quarterstaffs, scimitars, scythes, sickles, shortspears, slings, and spears.
The weapons list has been updated several times since then with releases such as the Advanced Players Guide and Ultimate Combat. Any official word on updating the druid's weapon choices? I was specifically wondering about the terbutje which themantically seems like a weapon a druid would use.
We're sticklers for the "offical rules" in my campaign, so if any Paizo developers have an opinion, I'd love to hear it.
