Once the chief is at the right Leadership level, do you have to do anything for him or her to point out a rare collectible or will they did it by themselves? Thx!

I had the same exact problem. You have to place your chief where the door is located at the top of the path. They will point, then rainbow will show over their head....start looking then.

I am having trouble getting a new tribal chief. I have dropped every on at the robe.

this thread should help you.
