The next time I referee Advanced Dungeons & Dragons, 1st Edition, Dungeons & Dragons Basic/Expert Set, Labyrinth Lord, or OSRIC, I will be using the following rules for generating attribute scores for player characters:
Method 1: Roll 4d6 (drop the lowest die) six times and assign to attributes as desired.
Method 2: Roll 4d6 (drop the lowest die) for each attribute in order. Choose one result to reroll and accept whichever is higher.
