Before You Jump In

The fight starts the moment you land, so prepare first:

  • Finish your upgrades. Complete anything you want to do in The Gap before starting.
  • Clear the Resonants. Beating them first means you enter the finale with your full combat kit.
  • Use the fast travel door. The Red Sand Island Fast Travel Door sits right before the Hedron, so you can pop back for supplies easily.

Getting to the Hedron

Once the objective updates, head to the gravity well at the northwest point of the zone. Use it to drop toward the Hedron on the far west of the map. It’s a long fall that narrows as you go, and you’ll land in the arena ready to fight.

How the Boss Fight Works

Here’s the twist: you never hit the Hedron directly. Instead, you fight the smaller enemies connected to it, and killing them drains the boss’s health bar. The fight has three phases across three arenas, each with its own bar.

Watch for these attacks:

  • Projectiles: shot in a straight line, so jump or stay low.
  • Sawblades: spinning blades that move back and forth.
  • Summoned foes: extra enemies that join the fray.

Tip: The center of the arena has a large cross-shaped hole, so watch your footing.

Phase Tips

  1. Focus the linked enemies. Keep your crowd control sharp, because this fight tests that more than boss dodging.
  2. Move when the arena splits. Once you deal half the health bar, enemies spawn on both sides of the arena. Use Reach to grapple across the airborne platforms and move to the other area.
  3. Keep dodging. Movement matters more than raw damage.
  4. Finish the center. Once a bar is empty, finish the Hedron’s center to move on.

Most players find this a fairly easy fight, so stay calm and keep moving.

After the Fight

Beating the Hedron completes the mission and drops your rewards, including the Untapped Worn Eraser, considered one of the best artifacts in the game. The story then continues with The End mission.
