and also, it’s a bit confusing to add the example using an “HD10 Red Dragon” (why do you include the “HD” in the example? should we use the HD somewhere?), and with a THAC0 of 11 would mean:
20 - 11 = +9 attack…
And just after that, the first monster example is a Red Dragon, and its +Attack bonus is… +8.
must be a small typo, but I think it may confuse readers at some point.
