Strike

Roll 3 twenty-sided dice and keep the highest result (this is Elven Accuracy — the half-feat that turns advantage into rolling three d20s instead of two; it only fires when you'd already have advantage). 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 19 or higher crits — the c19 part of the expression extends the crit range (Champion fighter's Improved Critical, a Hexblade's Curse, etc.). On a hit, deal 1 8-sided die, plus 5. On a crit, double the damage dice (the 1d8+5 becomes 2d8+5); flat modifiers stay the same.
