Well, with the incredible help of Reddit user /u/writerchild85, I've updated the PDFs for the original Creature Loot tables as well as adding one for Volo's and Tomb. The Volo's Guide PDF has a full crafting index, including every monster part in The Monster Manual and Volo's Guide. The Tomb PDF has all the Volo's Guide Monsters that appear in the book, instead of links like my articles.
Here are the finished products!
The Monster Manual Creature Loot
Volo's Guide Creature Loot
Tomb of Annihilation Creature Loot
I say "finished", but I'm sure I will go back and find mistakes or update language as I find errors. Fortunately, I'm keeping these on GM Binder now, which provides great support for updating these documents. I plan to keep these links up to date! And if you want ot modify them for your own purposes, you can always copy the source code and do so.
Thanks for reading! And thank you, /u/writerchild85!
