I worked these tables out for personal use, cause I love random character generation. And figured I’d share!
Roll a d6 for your highest stat (16):
1 – Strength
2 – Constitution
3 – Dexterity
4 – Intelligence
5 – Wisdom
6 – Charisma
You now have five unassigned attributes: Roll a d20 and assign your 15 and 13, respectively, to:
1 – 1, 2
2 – 1, 3
3 – 1, 4
4 – 1, 5
5 – 2, 1
6 – 2, 3
7 – 2, 4
8 – 2, 5
9 – 3, 1
10 – 3, 2
11 – 3, 4
12 – 3, 5
13 – 4, 1
14 – 4, 2
15 – 4, 3
16 – 4, 5
17 – 5, 1
18 – 5, 2
19 – 5, 3
20 – 5, 4
You now have three unassigned stats. Roll a d6 and fill them in as follows:
1 – 8, 9, 12
2 – 8, 12, 9
3 – 9, 8, 12
4 – 9, 12, 8
5 – 12, 8, 9
6 – 12, 9, 8
For bonus points, also considering choosing your class (and/or race, name, look, alignment, gear, and bonds) at random as well.
