This cheat sheet was heavily adapted from the work by Stephen McNabb on their Dark Soul 2 Cheat Sheet source code, and Zackary Kjellberg's Dark Souls 3 Cheat Sheet.
Much of the information here was adopted from the fextralife Elden Ring Wiki, and PowerPyx Elden Ring guides.
Apologies! This was mostly created for my own use, but I definitely saw benefit in making this public. I'm really trying to consolidate all collectible information into one place, however, this game is HUUUGGEE and it's a lot of work to track down every little piece I may be missing. If you'd like to contribute toward filling in any of the existing gaps, I'd surely appreciate it!
As of 03/08/2022, I know that a lot of links to the wiki are broken, or simply not present at all. I'll try to work on that, though it's not a huge priority of mine, compared to simply having the items able to be checked off.
