Verve Rigger utilises d6 die for it's system to promote ease of access and use. Though polyhedral dice are becoming more common, they still come at a premium cost compared to the d6 which can be found in every general store in bulk for practically pocket change.
Challenge Value represents difficulty and acts as a value an attempt must surpass to succeed.
Challenge Values are distributed generally by the following (but subject to change post play testing).
5. Easy
10. Simple
15. Balanced
20. Difficult
25. Very Difficult
30. Practically Impossible
A core part of Verve Rigger is focusing on idea that the player is the main driving factor of challenges and attempts. Traditionally through a D20, the player is a modifier to the result of the roll, you could get anywhere from a 2 to a 19 that results in your character not really feeling like it mattered until very late game.
Instead, Verve Rigger focuses on the player as the origin point of the attempt, and exerting effort to make up for and exploit any misgivings or advantages respectively.
A Challenge occurs when an objective needs to be met where there is an element of uncertainty involved. A player begins with their innate skill or ability with a certain task, and begins to build their effort. Beginning with the Challenge Dice and then, depending on the challenge, difficulty dice may be added to the dice pool, and finally players will be able to spend applicable cards in their hand in exchange for additional 1d6s to add to the attempt, this builds the Challenge Modifier.
To the Innate Skill or Ability the Challenge Modifier is added, and if it beats the Challenge Value the Challenge is succeed.
Below is a visual example.
We begin with the Challenge dice which represents the variance in an attempt without any additional effort.
In this example, green and blue d6 are effort from a combination of trained skills and the core ability being challenged, and the black d6 is the difficulty.
Adding effort is optional, and the difficulty added is a circumstantial occurrence, so this step will sometimes be skipped.
We roll the dice together and then subtract the total of negative from the total of the positive.
