Besides farming boss monsters and badasses for moonstones in Borderlands: The Pre-Sequel, there’s a very easy way to acquire moonstones that involves some very simple procedures. It's especially helpful if you've accidentally spent your Moonstones on a Moonstone chest and would like the game to reimburse you.
Requirements: Keep in mind that this trick only works on the PC version of the game. In order to receive your ‘loyalty bonus’, you’ll have to have Borderlands 1 or 2 installed on your rig with a save file.
Step 1: Start a new game and once on the character selection screen, quit to the main menu.
Step 2: Select your current character and continue your game.
Step 3: That’s it! You should receive a notification of receiving a free weapon (Blue in quality) and 10 moonstones.
Simply repeat the steps to accumulate unlimited moonstones and blue weapons.
