ChicagoWiz has a great post over at his blog where he references my Wilderness Alphabet and the excellent Kellri's Classic Dungeon Designer Netbook #4.
Furthermore, in the comments, Bob from Back to the Keep references a spreadsheet that he has made that automatically rolls d100 for each hex.
Being unable to resist tinkering, I took ChicagoWiz's table and I merged it with Bob's spreadsheet. I used a vlookup to make the results of the d100 roll populate in the hex.
Here's a screenshot:
You can download the spreadsheet for OpenOffice here. I could not get it to work in Excel and I don't know why. Perhaps later today I'll take another crack at it. If you know how to fix it, let me know.
Thanks a bunch to ChicagoWiz and to Bob for putting the table and the spreadsheet out there. I just mashed them together.
