That's what I thought it was, but when I calculated it, I didn't get the same answer as the book.
Also, the book doesn't factor in the chance to confirm a crit in the average damage. (If it did, the average damage would be different against the three different armor classes.)
It lists the average damage of the Dwarven Waraxe +2 for Tordek at 15.95 against AC 20, 26, AND 32.
If anybody has S&F, could you please demonstrate how they arrived at the numbers on table 4-2 for damage?
