Strike

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 10-sided die, plus 5. On a crit, double the damage dice (the 1d10+5 becomes 2d10+5); flat modifiers stay the same.
