¶ Check
There are three prepared check bags in the game, each with 10 cubes:
contains 5 black 
+ 5 neutral 
contains 3 + 7
contains 2 + 8
Each time you have to pass a check (for example, 
2), you take bag and randomly take out a specified number of cubes (the number after the sign, 2 in this case). If there are no black cubes (or 
another player's cubes) among the cubes drawn, it is a success - you have passed the check; otherwise - you fail. That is, you need to draw the cubes of either your color or neutral in order to succeed. If you fail to pass the check, you suffer negative consequences or lose certain opportunities.
Some types of checks are free but single-try, while others are multiple-try, but you have to pay for each attempt to pass it. Let's look at examples:
- 2 - single try check (you have only one attempt), you have to draw 2 cubes.
1 - single try check, draw 1 cube from the prepared battle bag.
- 5
3 - pay 5 to the bank before the check, then draw 3 cubes from the bag. If you fail, you can keep trying, paying 5 coins for each attempt.
- 31
| - you must have at least 1 in order to start passing this check. Draw 3 cubes from the bag. If they are all neutral cubes - you have succeeded. If you have drawn black cubes - pay 1 for each black cube in order to succeed.
If you don't have enough mead - you failed and have to discard all of your .
¶ Bag Upgrade
Before any check, you can discard 1 / experience 
/ action to take a level up bag. Therefore, in order to take bag you you discard two items in any combination (e.g., 1 + 1 experience ).
In some cases, the check is performed with a prepared battle bag . Then the bag cannot be upgraded.
¶ Complexity
Complexity of the check is the number of cubes you have to draw from the bag while passing this check. For instance, check 2 has complexity of 2. The more cubes you draw, the greater is the probability of drawing a black cube, thus leading to failure.
There are some conditions that reduce / increase the check complexity by 1, they are called simplifying factors / complicating factors.
For example, while spreading a religion, a complicating factor is the fact that another player controls that province or another religion is already there, therefore, it forces you to draw an extra cube.
You may discard one or more action / experience to reduce the complexity of any check by 1 for each one discarded. However, the complexity cannot be reduced to zero.
