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. On a crit, double the damage dice (the 1d8+3 becomes 2d8+3); flat modifiers stay the same.
