Strike

Roll 2 twenty-sided dice and keep the higher result (this is advantage — granted by Faerie Fire, Reckless Attack, Pack Tactics, hidden attackers, and a handful of other sources). Add +9. Compared against AC 17: you hit if the kept d20 face plus the bonus totals 17 or more (so the d20 needs to land on at least 8). A natural 20 always crits, regardless of AC. On a hit, deal 2 6-sided dice, plus 5. On a crit, double the damage dice (the 2d6+5 becomes 4d6+5); flat modifiers stay the same.
