Lost Marbles are something you can find in the different zones you’ll visit during your adventure through Tiny Tina’s Wonderland. Here you’ll be navigated to the Lost Marbles which are scattered around Fearamid.
Lost Marble Location #1 - Catwalk To Obliteration
Head to the Catwalk To Obliteration Fast Travel, then walk to the end of the wooden platform and look to the right to see a few pipes. Here you can drop down onto it to reach another wooden platform to find the first Lost Marble!
Lost Marble Location #2 - Final Steps
Head into the corridor which takes you from the Soul Collection Nexus to the Final Steps and you’ll find the Lost Marble sitting behind a fence.
