How do you complete the "The Wisdom of the Elders" side mission without failing?

The Wisdom of the Elders is a unique side mission in Red Dead Redemption 2 that involves helping a Native American elder named Rains Fall. This mission is part of the larger storyline involving the Wapiti Native American tribe and requires careful attention to avoid failing. The mission becomes available during Chapter 6, after completing the main mission ''The Delights of Van Horn.'' To start, head to the Wapiti Reservation, located northeast of Valentine, near the Dakota River.\n\nWhen you arrive at the Wapiti Reservation, you will find Rains Fall near his tent. Speak to him to initiate the mission. He will ask you to accompany him to collect medicinal herbs in the nearby wilderness. This is a stealth-based mission, so you must avoid detection by the U.S. Army soldiers patrolling the area. Equip yourself with a bow or a silenced weapon, as loud gunfire will alert the soldiers and cause the mission to fail.\n\nFollow Rains Fall as he leads you to the herb locations. The first herb, Yarrow, is found near the riverbank. Stay crouched and use the environment for cover. If you encounter soldiers, use Dead Eye to mark and eliminate them quietly. Rains Fall will guide you to the next herb, which is located in a more open area. Be cautious, as soldiers patrol this region more frequently. Use rocks and trees to break line of sight and avoid detection.\n\nAfter collecting the second herb, Rains Fall will ask you to retrieve a third herb from a nearby cave. This is the most challenging part of the mission, as the cave is heavily guarded. Approach the cave entrance slowly and use your binoculars to scout the area. Take out any soldiers silently before entering. Inside the cave, you will find the final herb, but be prepared for a surprise ambush. Stay alert and eliminate any threats quickly to protect Rains Fall.\n\nOnce all the herbs are collected, escort Rains Fall back to the Wapiti Reservation. Avoid the main paths and stick to the forested areas to minimize encounters with soldiers. If you are detected, prioritize protecting Rains Fall over engaging in combat. Use Dead Eye to take out multiple enemies quickly and keep moving. Upon returning to the reservation, the mission will conclude, and you will receive a reward.\n\nCommon challenges during this mission include being detected by soldiers or failing to protect Rains Fall. To avoid detection, always stay crouched and use the environment for cover. If you are spotted, use Dead Eye to eliminate threats before they can alert others. Additionally, ensure you have enough ammunition and healing items before starting the mission, as combat can be intense.\n\nPractical tips for success include using the bow for silent kills, equipping the right weapons, and staying patient. Avoid rushing through the mission, as stealth is key. Pay attention to Rains Fall''s movements and follow his lead. By staying cautious and prepared, you can complete The Wisdom of the Elders without failing and enjoy this meaningful side mission in Red Dead Redemption 2.
