Chance Roll

Chance rolls use dice to determine random outcomes for uncertain events.

Chance rolls can be used to determine game aspects of the game that do not include direct participation by the players. They can also be used to introduce random narrative elements that can help direct the story in unpredictable ways. They reinforce the role of using dice to make the game feel dynamic.

Using Chance Rolls

Chance rolls can be used for a variety of purposes.

IMPARTIAL CONSEQUENCES: Pick a random condition for a common consequence. This could include choosing the type and location of damage from a physical attack, the effect of poison or disease, or a wild magic event from the failure to cast a spell.

DYNAMIC SCENES: Determine dynamic elements when defining a scene and situation. This could include environmental factors such as time of day and weather conditions, or the number, attitude, and disposition of non-player characters towards the group.

RANDOM ENCOUNTERS: Unexpected events or incidents such as a random encounter with an obstacle or adversary, or a change in the environment such as a sudden blackout or a minor earthquake.

WHAT ARE THE ODDS?

Not every random element of the game requires a chance roll. There are times when the host will want to exert control over distinctive narrative elements within a prepared scene. These details may be essential to establishing the situation that players face.

Host can use this simple rule of thumb. If the players ask a question, and the answer is not pre-determined, consider using a chance roll.

Making a Chance Roll

Chance rolls are made using a D100, and potential outcomes are assigned a percentile chance between 1 and 100.

Chance rolls work particularly well for simple binary decisions. Ask a question and assign a percentile chance to the preferred outcome. For decisions with large sets of potential outcomes, the host can prepare a random table.

Random Tables

Random tables can be used to match the results of a chance role with a list of pre-generated outcomes.

EXAMPLE: MAGIC 8 BALL

The following random table simulates a Magic 8 Ball producing a gradient outcome to any question. The table contains 10 potential outcomes that can also be used to determine a random difficulty target number from 1 to 10.

ROLL	RESULT
01-05	ABSOLUTELY CERTAIN - The stars align, signaling resounding success.
06-15	HIGHLY LIKELY - Favorable omens suggest success is close at hand.
16-30	OPTIMISTIC - Good chances, with more signs pointing towards success.
31-45	SOMEWHAT HOPEFUL - A bit better than average chance of success.
46-55	BALANCED ODDS - Success and failure are equally likely.
56-65	UNCERTAIN - The outcome is hard to predict, could go either way.
66-75	SOMEWHAT DOUBTFUL - Challenges ahead, success will require effort.
76-85	PESSIMISTIC - More signs of failure, success will be hard to achieve.
86-95	HIGHLY UNLIKELY - Success is a long shot, with most signs pointing to failure.
