Third, Zaknafein's player clearly rolled those stats rolling 3d6, in order. Believe him, his brother was with him when he rolled, he saw the whole thing, no cheating involved!![]()
Not to nitpick, because I agree with you mostly, well, so actually, JUST to nitpick. about the odds of it happening :
STR 20, DEX 22, CON 16, INT 19, WIS 12, CHA 14
If we suppose, as a CR 16 threat, he is able to get epic boon. At CR 16 he should be bordering on epic. And he certainly got access to some legendary magical items, while the various tomes are just "very rare". Let's suppose that he got two +2 stat increase from these source, and he got the 7 regular ASIs over his career as a fighter, he could have started with STR 16, DEX 18, CON 14, INT 17, WIS 10, CHA 12. Having these stats with 4d6 drop lowest is lucky, but not impossible. If I calculated this right, the ods are 1 in 50,000. Exceptionnal, yes. Impossible, well, I guess Menzoberranzan being a drow metropolis it should be statistically possible. And if PCs are exceptionnal, they could be facing exceptional threats as well. Hercules wasn't tasked to clean a regular stable.
Unfortunately, one of the area Zaknafein fails to be exceptional is "writing an interesting background".
