I tried to avoid it, because I am down to 3500 seed The quest says 3 newest, so I was hoping to avoid it, and technically Wolf Shrine fits that requirement, being one of the 3 newest cultural buildings. Unless they want the 3 of the same newest. Dang. They should have just named the building directly/specified exactly what they need instead of being vague about it.@mura32 Yes, no diamonds required to fulfil that quest. I also built a Desert Fortress.
Thank you for the reply, Yogi Dave and iamthouth.
