Roll 1 twenty-sided die. Add +9. Compared against AC 15: you hit if the kept d20 face plus the bonus totals 15 or more (so the d20 needs to land on at least 6). A natural 20 always crits, regardless of AC. On a hit, deal 1 8-sided die, plus 5. On a crit, double the damage dice (the 1d8+5 becomes 2d8+5); flat modifiers stay the same.

A natural 20 always crits, regardless of AC. On a hit, deal 1 8-sided die, plus 5, plus 2 8-sided dice (the rider — extra damage on top of the base, doubled on crit just like the base dice). On a crit, double all the damage dice (the 1d8+5 becomes 2d8+5, the rider 2d8 becomes 4d8); flat modifiers stay the same.
