Mau's skills are all pretty self explanatory, it's nice. This skill includes everything from felling trees to how long logs take to cure to actually processing lumber into planks or posts or a canoe. He can make excellent outrigger canoes and decent other timber products. He can also make an okay wooden hut, and does not need any metal nails for this. He will now be proficient at learning new types of woodworking (such as making furniture) from others, or will be able to figure it out from examples, as well.
