We're finally getting this to the table this week, but I have a couple questions that I'm hoping to resolve first... just in case they come up. I searched but haven't found the answers, so any help is appreciated!
1) In light of Jay's post from 2011 (quoted below), can you place on the mine a "pair" made up of a single master and a single regular unit, and then collect only one resource? Or would you have to put the unmatched master somewhere else?
You can only place elves in the Forest, dwarves in the Quarry and pairs of each in the Metal Mines.
2) Just to confirm - you don't place a worker on a guild space to build it. You only have to pay during the actions phase. In fact you could build a guild that has someone else's worker on it still.
3) Also just to confirm - A gnome locked ability that doesn't have a plank (like the blacksmith) doesn't require a worker be placed to use it, while a card like the Inn has the plank itself locked, and once unlocked would require a worker to use.
