We are still gaining experience with guild islands, but we did the following.
- Built a tanner, lumbermill, stonemason, and weaver in the center plot.
- Built a smelter and toolmaker next, after upgrading.
- Built a cook and some other misc. buildings.
Feeding your workers is very important, otherwise you can’t use them. Have your guild members chip in their carrot soup to get the food levels up!
