The First Firewall

Before starting the quest, you’ll have to collect 4 DVALIN relic fusion rifles and give them to the Gunsmith. They drop randomly in locations on Earth, Mars, Venus and the Moon. This will open up The First Firewall quest on Earth, but only on certain days. If you miss the window of opportunity, you can try tagging along with someone who already activated/finished it – when you complete it, you’ll be able to finish the rest of the quests normally.

When you’ve finished the quest, you’ll obtain the Curious Transciever.

Curious Transciever Codes

In order to progress, you’ll need to input 4 codes into the Transciever. These codes correspond to the spawning order of the knights in the previous quest (Hive is upper, Taken is lower).

This will unlock a quest called Shadow Fall, which requires you do reach the top of Devil’s Spire in under 4 minutes. You’ll be rewarded with an IKELOS fusion core.

How to fix Ikelos Fusion Core

You need to get 5 parts from different activities to repair the core:
  • Heavy Power Coupling – You can get it by dismantling a legendary or exotic heavy weapon.
  • Ionized Shell Harmonics – Finish the Archives quest on Venus to get it (any difficulty will do).
  • WARSAT//MK19/TERRA/RSPN – Go to Earth and do the Defend the Warsat public event.
  • WARSAT//MK19/LUNA/RSPN – Do the Defend the Warsat event on the Moon, and you’ll get it.
  • WARSAT//MK19/MARS/CHLM – The final part is obtained by finishing the Defend the Warsat event on Mars.
Finding them all will grant you the Reassembled IKELOS Fusion Core, which you need to take to the Gunsmith. After a daily reset, he’ll give you the next quest – The Sleeper Stirs. It will task you with completing the Fallen SABER strike at Light level 280, and reward you with a Sleeper Simulant Weapon Frame. When you bring this item to the Gunsmith, he’ll give you the exotic fusion rifle of your dreams.

    two questions, 1 what days can you do it on? 2 do you have to get all of the dvalins in one day?

      2) I got the DVALINS quite randomly just patroling. 3 days a go I read a guide how to get the Simulant and went to venus to patrol con the Citadel. In 10minutes I got a DVALIN, brought it to the Gunsmith and tada! It was the 4rth one so I could start the missions.

      1) I just didi it and I need to wait a week so the Gunsmith will give me the mission. I needed 2 afternoons to complete all missions, not including the time getting the DVALINs. ANyway I;d say do it on weekend / monday-thursday so you don;t wait as long.
