A Master in Imperialism 2 is the top type of worker, with productivity 8.

He needs a luxury to maintain that productivity: fur hat, each unit created from two units of fur or (if you are lucky) bought in the market.

Training a journeyman to become a Master requires the appropriate technology, Master Artisans, and $1,000 and 10 pieces of paper. It is a good investment if you can keep up the supply of fur. There is not much fur in the Imperialism 2 world. It is found in only a few provinces near the North Pole and the South Pole.
