Stress die
Rolling a stress die refers to a method of the Ars Magica game mechanics to determine the outcome of an action or event under stressful circumstances. A stress die carries with it the possibility of spectacular success or catastrophic failure.
First, you roll a single ten-sided die, which is typically numbered 0 through 9. A zero is special: there is a chance the character will Botch, and the player must roll botch dice to see whether that happens. Even if no botch occurs, the roll is treated as zero.
A 1, on the other hand, allows the player to roll again, doubling the result of the next roll. Additional 1's multiply the next result by four, eight, sixteen, and so forth, until a number other than 1 is rolled. All other numbers (2-9) count as their actual values. On the second and subsequent roll, a zero stands for a value of 10.
- Example: You roll 3. The result is 3.
- Example: You roll 0. The result is 0, and you must roll a certain number of botch dice determined by the Storyguide to see if you botch.
- Example: You roll 1, roll 0. The result is 0, and you must roll a certain number of botch dice determined by the Storyguide to see if you botch.
Unlike a Simple Die that is used in relaxed situations, a Stress Die is used to reflect stressful circumstances. Combat and most spell casting are both examples for the use of a Stress Die. Due to the open-ended multiplication from rolling consecutive 1's]], a stress die can (rarely) yield spectacular results.
