Borderlands 4 Crystal Brawl Main Story Mission Walkthrough, Follow Amara and Get Eridium

In the chaotic world of Borderlands 4 Guides, the Borderlands 4 Crystal Brawl main story mission demands sharp focus amid the loot-driven frenzy. Begin by locating Defiant Calder at Beltans Bore in the northeastern part of the Lowlays map to start the quest.
Crystal Brawl Quest Start Location:

After speaking with Calder, head far south, past the Heritage Opus, into the mountain region on the eastern edge of the map. Work through the mounds until you reach the Bones of Sanctuary, where Amara awaits. She joins you, guiding the way in this Borderlands 4 crystal brawl guide.
Bones of Sanctuary (amara location):

Follow Amara northeast to the Windmills area, which leads to the Temple of the Predecessors. Here, the mission becomes a gauntlet of combat as you take down waves of guards while Amara unlocks pathways and doors. Along the route, look for a side objective to destroy Eridium mining drones, which are attached to large purple crystals and easy to spot in this borderlands 4 crystal brawl walkthrough.
Temple of Predecessors Location:

The temple's linear path continues with repeated guard encounters, always trailing Amara as she clears the way. Eventually, you reach a chamber with a purple crystal inside a machine. Shoot or toss a grenade at it to break it apart.
Next, find two switches in the front left and right corners of the room, near the wrecked machine. Climb to the second floor, stand on a tall cylinder, and perform a double jump followed by a ground pound—left Ctrl on keyboard or the equivalent controller input—to hit the first switch.
All Relevant Areas in Boss Room:
After landing, look up at the central machine to spot an open hatch. Throw a grenade inside or shoot the crystal within if you can get a clear angle. Repeat the process on the other side: climb, double jump, ground pound the second switch, and destroy the second crystal.
With both crystals destroyed, a new path opens on the second floor at the back of the machine. Exit through this route, avoiding the way you entered, and run a short distance forward.
