Saddleback and Immortal Boneface (Meathead Riders) is an optional boss encounter located in The Old Scrape Ripper Drill Site, Cuspid Climb in Terminus Range. You can access Ripper Drill Sites as soon as you discover them on the map.

All Ripper Drill Site Locations
Immortal Boneface is invulnerable while mounted on Saddleback, so focus on Saddleback first. He may dismount occasionally, but his shield will rapidly regenerate as long as Saddleback is alive, making it inefficient to attack him until Saddleback is defeated.
From the arena entrance, head to the far left side. This enclosed spot has only one entry path, making it easier to avoid being surrounded and overwhelmed by enemies.
