Carefull Roll

📜 For those who seek stability in an unpredictable world.

Mechanic:

  • When rolling an attack, ability check, or saving throw, roll two d20s.
  • Choose the result closest to 10 (averaging the number in a tie).

Effect:

  • Reduces extreme failures and successes, keeping rolls near the middle range (8-12).
  • Perfect for strategic, careful characters who prefer consistent results over chaos.
  • Makes nat 1s and nat 20s far less likely, ensuring fewer catastrophic failures.

Average Roll:

  • Expected value: ~10.5 (compared to a standard d20 average of 10.5).
  • Rolls tend to cluster around 8-12, reducing variability.

Example:

  • You roll a 5 and a 15 → You take the 15 (closer to 10).
  • You roll a 3 and a 17 → You take the 3 (closer to 10).
  • You roll a 10 and a 14 → You take the 10 (exact middle).

🎭 Best for: Strategic thinkers, scholars, monks, and those who fear the chaos of fate.
