Strike

Roll 1 twenty-sided die. Add +0. 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 15). A natural 20 always crits, regardless of AC. On a hit, deal 2 6-sided dice. On a crit, double the damage dice (the 2d6 becomes 4d6); flat modifiers stay the same.
