My current character, Xerthos, a Dragonborn Paladin, is probably the best I’ve rolled up (I’m usually DMing, so this is like my 5th character in 40-so years).
17/10/12/12/13/20 after stat mods.
Prior character for the same campaign had the highest stat of 12 (after racial mods - human) as a monk. He lasted much longer than I expected (over 2 levels, I expected him to die in his first combat) and was surprisingly effective. Wouldn’t have minded playing him longer. Ended up dying in a combat when he critically failed a death roll.
