Tactical Analysis & Mathematical Context
In tabletop gaming, understanding the mathematical distribution behind your rolls allows you to make informed risk-reward decisions. Whether balancing spell slot usage in D&D 5e, evaluating an attack profile in Warhammer 40k, or weighing trade routes in Catan, knowing the exact probability mass function (PMF) turns guesswork into strategy.
Frequently Asked Questions
Is Lethal Hits or Sustained Hits better against high toughness?
Lethal Hits is dramatically better against high Toughness targets (where you would otherwise wound on 5+ or 6+), because critical 6s completely bypass the difficult wound roll. Sustained Hits is superior against low Toughness targets where wound rolls are already easy (2+ or 3+).
