Roll log
Rolls use JavaScript Math.random — fine for games, but not cryptographically secure. Results re-roll every time an input changes.

Formula
Total = Σ(1 + floor(random() × sides)) for each die + modifier
Pro tips
- • Roll 4d6 and drop the lowest for classic D&D ability scores.
- • The expected value of a single dN roll is (N + 1) ÷ 2 — a d6 averages 3.5.
