How do these bonuses work?
I can see in that screenshot that the tile gives two bonuses.
Green arrow - 3 military.
Orange diamond - 1 to wealth.
What does the green arrow and a yellow diamond mean? I moved my mouse over them but get no tooltip.
I think the green arrow means you get this bonus (3 military) on tiles adjacent to this tile and not on the tile itself?
What about the orange diamond, does that mean the bonus is actually on the tile itself but not the adjacent tiles?
So if this is correct you'd be looking to put a wealth producing building on the tile and military tiles around it?
Also does the tile itself, in this case caverns, give the adjacency bonus, so you would get the military bonus straight away on adjacent tiles, or do you have to actually place a building on the tile to get the adjacency bonus? The former makes more sense to me.
