The problem specification for the D&D Character exercise says to roll 6 times (line 7 and line 14), but examples (lines 16-21) show 4 throws for each ability: problem-specifications/exercises/dnd-character/instructions.md at main · exercism/problem-specifications · GitHub
Three character has six abilities. Each ability is calculated by rolling/throwing four dice. You throw four dice for each ability, so there are six “throws” of four dice.
