How do you trigger the "A Test of Faith" stranger mission?

The ''A Test of Faith'' stranger mission in Red Dead Redemption 2 is a unique and intriguing side quest that involves hunting for dinosaur bones scattered across the game world. To trigger this mission, you must first encounter the stranger who initiates it, Deborah MacGuiness, a paleontologist. This mission becomes available in Chapter 2, after you have completed the main story mission ''Polite Society, Valentine Style.''\n\nTo start the mission, head to the area near the Dakota River, specifically to the northeast of Valentine. Look for a small campsite near the riverbank, where you will find Deborah MacGuiness. She will be examining a dinosaur bone and will ask for your help in finding more. This interaction will officially begin the ''A Test of Faith'' mission.\n\nOnce the mission is triggered, your task is to locate and collect 30 dinosaur bones scattered throughout the game world. These bones are hidden in various locations, often in hard-to-reach or obscure areas. Each bone you find will be marked on your map, but you will need to explore thoroughly to locate them all. Some bones are found in caves, while others are on cliffs or in remote wilderness areas.\n\nTo make the search easier, use your binoculars or the Eagle Eye ability to highlight the bones. This will make them easier to spot, especially in dense foliage or rocky terrain. Additionally, some bones are located near landmarks or points of interest, so keep an eye out for these as you explore.\n\nOne common challenge players face is locating all 30 bones due to the vastness of the game world. To overcome this, consider using an online map or guide that marks the exact locations of each bone. This can save you a significant amount of time and ensure you don''t miss any. Another tip is to focus on one region at a time, systematically searching each area before moving on to the next.\n\nOnce you have collected all 30 bones, return to Deborah MacGuiness at her campsite. She will reward you with a unique dinosaur bone knife, a valuable and rare item in the game. Additionally, completing this mission will contribute to your overall completion percentage, making it a worthwhile endeavor for completionists.\n\nIn summary, to trigger the ''A Test of Faith'' mission, visit Deborah MacGuiness near the Dakota River after completing ''Polite Society, Valentine Style.'' Collect all 30 dinosaur bones using your binoculars or Eagle Eye, and return to Deborah for your reward. Use online guides and focus on one region at a time to make the search more manageable. This mission not only offers a unique challenge but also rewards you with a rare item and contributes to your game completion.
