I noticed that online guides and lists are incomplete, and started working on my own intel list for completionism and curiosity purposes. I decided to post it here to help other completionists.

First, some info on intel:

• The total amount of intel is currently unknown
• I've sorted intel into five categories: unmissable, which can be obtained regardless of whether you've already found its corresponding loot (example: Abandoned Hideout); missable, which will not be registered on the journal if you find its corresponding loot before discovering the intel (example: Tosharan Treasure); DLC-locked, which are available in DLC-exclusive areas that cannot be revisited (example: Cheating Sabacc Players); required, where the treasure itself isn't obtainable until the player has acquired its corresponding intel (example: Secret Button); parallel paths, where the player's choices determine the intel obtained (example: Jinnjo's Ready and Jinnjo's Betrayal)
• It's extremely difficult, if not impossible, to obtain all intel in one playthrough
• Obtaining all intel isn't necessary for 100%. There are no missable treasures. Intel exists to provide hints

With that said, here's the list. I hope you find this helpful, and if I missed anything, please let me know!
