Strike

Roll 1 twenty-sided die. Add +5. Compared against AC 13: you hit if the kept d20 face plus the bonus totals 13 or more (so the d20 needs to land on at least 8). A natural 20 always crits, regardless of AC. On a hit, deal 1 8-sided die, plus 3, plus 1 6-sided die (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+3 becomes 2d8+3, the rider 1d6 becomes 2d6); flat modifiers stay the same.
