This came up a few times for us in our first play. When the event says max X grain, does the +1 tile mean that when you take the gain action you get the region grain to a max of the event limit +1 from your turn order tile, or is the bonus included in the max cap?
Similarly, does the reward that turns the buy 5 cubes action into buy 6 cubes completely override the event that makes the buy 5 cubes action into buy 3 cubes? Does it get treated as a +1 (meaning that that start tile plus that event means the action would be as normal)?
I couldn't find a clear answer in the rulebook.
Check the upper right-hand corner on page 7 of the rulebook. The event is applied first, then the bonus is added. So for gold and grain, you would get the maximum +1. There is an example on page 7.
The army bonus gives 6 armies. The event does not affect this bonus, the player would still receive 6 armies.
