If you want a simple way to do a "random" Demigod, open Excel, make the following table:
| Demigod |
Less than or = to |
| 1 |
0.125 |
| 2 |
0.250 |
| 3 |
0.375 |
| 4 |
0.500 |
| 5 |
0.625 |
| 6 |
0.750 |
| 7 |
0.875 |
| 8 |
1.000 |
Where Demigod 1-8 is the demigod, and the numbers in the right column are equal to (8/1)(Demigod Number) or (.125)(Demigod Number).
Then, in another cell, type (without the quotes) "=rand()"
This will give you a random digit between 0 and 1. Wherever this digit falls is the Demigod you get!
