It’s cool that advantage/disadvantage affects the rolls more towards mid-range than the extremes. A little more complicated than it may appear. I think advantage/disadvantage is one of the greatest innovations in modern rpgs. It gives a substantial advantage, but, you really don’t know how much of an advantage until you roll. Simple but interesting! Anyway, thanks for another great video’
Rolling one specific number twice is the one thing (1/6×1/6=1/36 in 2D6), rolling doubles (1-1,2-2,3-3,4-4,5-5,6-6 in 2D6) is another (as each double has 1/36 chance, rolling any of the doubles have 6×1/36=1/6, the same chance as the number of sides the dice have). Chances of rolling doubles: 2D4 (1/4), 2D6 (1/6), 2D8 (1/8), etc. This is relevant in systems that rolling doubles trigger especial effects.
