During the Season of Plunder (S18), the best loadout is:

  • A Kinetic Sniper Rifle
  • Any Solar Pulse Rifle
  • Gjallarhorn or Xenophage
  • A Solar 3.0 Build

In the Excavation Site XII Lost Sector, you’ll run into Unstoppable and Barrier Champions. Any Pulse Rifle is great at stunning the Unstoppable Champion.

If you have access to the Dares of Eternity, the Solar Pulse Rifle (BXR-55 Battler) is what we recommend. It’ll do extra damage because of Solar Burn, but it’s not necessary. Any Pulse Rifle will work because it’s only for stunning Unstoppable Champions.

You’ll use your Gjallarhorn or Xenophage on the Barrier Champion and final boss. Both are fairly easy to obtain.

Needless to say, these aren’t easy, and the least you should do is ensure you have a reasonable Power Level. By reasonable, we mean no less than 10 Power Levels below the recommended levels. If you find yourself struggling, work on increasing your Power Level as much as possible and focus on Legend Lost Sectors.

Excavation Site XII Lost Sector guide

The Excavation Site XII Lost Sector is really easy with Solar 3.0. All of your kills come from your Solar abilities and Gjallarhorn (or Xenophage). If you’re new to running Lost Sectors, your Pulse Rifle will also help.

There are a lot of Unstoppable Champions in this Lost Sector. They should be stunned with your Glaive and then killed with a Gjallarhorn rocket  (or with a couple of Xenophage shots). When you get to the Barrier Champion, you can kill it before it uses its Barrier. Keep in mind you only have a very short window to do enough damage.

Gjallarhorn Exotic Rocket Launcher

The best way to do this is by using your Solar grenade and Heavy weapon at the same time. If you’re not fast enough, you can still break the Barrier with Anti-Barrier Sniper Rifle Rounds.

If you use only one Gjallarhorn shot per Champion, you’ll have plenty to kill the boss quickly. You can buff your damage even more if you kill the Nightmare Cabal next to the boss first.

This Nightmare enemy will drop an orange orb once killed. This ball will buff your damage against the final boss for a few seconds.

Lost Sector Rewards

As a reminder, completing Legend or Master Lost Sectors solo is the only way to acquire several specific Exotic armor pieces. While our Lost Sector Exotics guide covers them all, including their rotation for the remainder of the season, these are all Lost Sector Exotics available today:

Excavation Site XII Summary

If this guide had too much information and you can only remember one sentence, these are the highlights:

Featuring a Solar burn modifier, the Excavation Site XII Lost Sector features Solar-shielded enemies and Unstoppable and Barrier Champions. Due to its length to complete and difficulty, this is one of the best Lost Sectors to farm.

Hopefully, you now have everything you need to know how to best clear this Lost Sector to farm exactly the type of Exotic armor you need.
