"At the end of the game, the player may assign either 1 Specialist tile that matches either color or 1 Cartographer and 1 Excavator - each of a different color shown."
Does this mean I can assign 2 correctly colored Cartographers or 2 correctly colored Excavators or 1 of each to the Mission tile?
1 of each.
They are very similar to ancient maps except it's two different colors and I do not believe you can assign magical items (from the Hidden Temple - if it's in play) to it because the rules say 'as long
as they are assigned to an Ancient Map' and the dual maps are 'Mission Tiles'.
Although I wouldn't mind the designer/publisher confirming that :)
Example: Purple and Orange Dual Map.
You could place a Purple Cartographer and an Orange Excavators
