Use Shock and Corrosive Weapons
Core Observer’s health bars alternate between shield and armor. Use Shock weapons to quickly strip its first shield bar, then switch to Corrosive for the armor bar. Once the armor is destroyed, swap back to Shock to finish the fight.
Kill Witness Enemies
Core Observer will summon flying Witness units that chase you down and fire ranged attacks. Focus on eliminating them quickly, as they can deal punishing damage if left alone.
Take Cover From Projectiles
Core Observer fires laser beams and volleys of projectiles that can quickly drain your health. Use the machines and structures around the arena as cover to avoid taking damage.
