Eliminate Hive until you find a way to clear the blocked path.
- A Tomb Ship will tear into reality nearby and deposit a large number of Hive for the Guardian(s) to deal with.
- You will be facing a Revenant Knight and 4 Acolytes.
- A careful grenade toss or another Area of Effect attack can be devastating here.
- A few Thrall and Unhallowed Acolytes will follow after that.
- They are lead by a Revenant Wizard and an Ogre.
- Keep on guard because there is also a group of Cursed Thrall and Acolytes coming from a side of the cavern as well.
- Defeat them to make it easier to deal with the Boss Ogre.
- Killing the Ogre will get it to drop a Worm you can bring to the back section of wall with the Orange Growth.
- Interact with the growth while holding the worm to clear the way forward.
- Move back from the wall because it will explode, potentially with lethal force.
- This will clear the path forward for you.
