- With the passage open, run on through the corridor.
- This will lead you to a large chamber with a number of Fallen Containers and lots of trapped Heavy Ammo scattered throughout the area.
- You will begin with the Trickster nearby you.
- Go and attack her to start doing damage.
- After a round of doing some damage, she will teleport away, reforming somewhere else.
- With some damage done, the Trickster will vanish briefly from the arena.
- She will then bring in a number of Scorn that are immediately going to attack the Guardian.
- You will be facing Ravagers, Stalkers, Courier, and the occasional Chieftain.
- Remember the Couriers drop Explosive Engrams.
- Collect these, and if you can, throw them at the Trickster.
- Just fight on, dealing with the teleporting and additional waves of Scorn that will come after the Guardian.
- Keep attacking until the Trickster falls.
