1.) Set the game to Solo (Important)
2.) Start a Vault bounty from Mother
3.) Proceed, until you enter the Vault, and kill the Necramech
4.) Go around the Vault slowly until you find 1 Scintillant (Listen for the buzzing noise). Being the Host of a Solo game, there is a guaranteed spawn chance. Remember where it is (Important!!!) – Finish the vault (Optional)
5.) Exit the Vault, and start a Vault bounty (Note: Not the “Kill the Necramech” bounty, but the new “Do quests inside the Vault” bounty)
6.) Go into the Vault – The Scintillant you found in Step 4 will have respawned
7.) Enter the bounty circle to activate the bounty
8.) Travel back to the surface using one of those suction-extracty things and travel far enough away till you abandon the bounty
9.) Proceed to Step 5
Every loop will guarantee 1 Scintillant (Start bounty, collect Scintillant, enter circle, evac, fail bounty, loop)
Enjoy 🙂
