Mastering Shadowrun Extended Tests Through Advanced Statistics
Shadowrun is a game of calculated risks, high stakes, and complex dice pools. When runners face daunting challenges requiring extended tests—such as complex deckding intrusions, extended repair operations, or prolonged magical rituals—understanding the underlying mathematics can mean the difference between glorious success and catastrophic failure.
Why Extended Tests Require Statistical Planning
Unlike simple tests, extended tests accumulate successes across multiple time intervals. If a player fails to reach the target threshold before running out of intervals, the action fails entirely. Advanced statistics help players determine whether their current dice pool is sufficient, or if they need to spend Edge, acquire gear bonuses, or call for team support.
Frequently Asked Questions
On a standard six-sided die, rolling a 5 or 6 counts as a success, giving a base probability of approximately 33.33% (or 1/3) per die rolled.
Exploding sixes allow you to roll an additional die when a 6 appears, effectively increasing the expected value and raising your overall success probability across extended intervals.
You should deploy Edge when statistical projections show your success probability falling below acceptable thresholds, or when facing high interval penalties in critical campaign moments.
