How to get Ergo Sum in Destiny 2
To get the Ergo Sum sword in Destiny 2: The Final Shape, you must first complete the main campaign of The Final Shape expansion. After finishing the campaign, return to The Lost City and speak with your Ghost to start the “Destined Heroes” questline, which is essential for unlocking the Ergo Sum. This quest involves multiple steps, including completing subquests like “Queens, Part 1,” “Found in the Dark,” “Lost in the Light,” and “Queens, Part 2,” which feature puzzles and combat challenges. Upon completing these quests, you will be able to claim the Ergo Sum exotic sword from a veiled statue in The Sacarium area of The Pale Heart. This sword is unique as it uses special ammo in the energy slot and can have random perks, elements, and frames, making it highly versatile and sought-after.
Unlocking Ergo Sum is fairly straightforward in Destiny 2: The Final Shape. Here’s a quick glance at everything you’ll need to do:
- Complete The Final Shape campaign
- Pick up the “Destined Heroes” quest
- Complete “Queens, part 1”
- Complete the “Found in the Dark” quest
- Complete the “Lost in the Light” quest
- Finish “Destined Heroes” by completing “Queens, part 2” to get Ergo Sum
How to complete ’Queens’ and ’Destined Heroes’ in Destiny 2
To complete the “Queens” and “Destined Heroes” quests in Destiny 2, start by finishing the Final Shape campaign, which unlocks the “Destined Heroes” questline. Begin with “Queens, Part 1,” an adventure where you must redirect incoming elemental damage to matching Hive runes by blocking attacks with a Hive Sword, empowering Arc, Solar, and Void runes to progress. Afterward, complete additional quests like “Found in the Dark” and “Lost in the Light” to enhance your Prismatic abilities. Finally, proceed to “Queens, Part 2,” another mission that advances the questline toward obtaining the Ergo Sum exotic sword. These missions involve puzzle mechanics and combat but do not require endgame builds, making them accessible for most players.
Once you land back in The Lost City after the campaign, talk to Ghost and he’ll give you some lore and then offer you the “Destined Heroes” quest. From here, tune into the radio, and then start the “Queens, part 1” quest nearby.
Queens isn’t a story mission but is as straightforward as one, save for a segment about unlocking Hive runes. Tip: If you kill one of the Hive Knights, they’ll drop a sword, which you can use to redirect elemental damage into the Hive runes.
The game will give you a bit of a tutorial about this, but one thing it doesn’t tell you is that you need to turn on all three of the runes in that particular element before the mission will progress. Keep going until you finish “Queens.”
Talk to Micah-10 once you load back into The Lost City and pick up “Convalescence: Rootbound,” which will be important for getting a different Exotic, Microcosm. From there, talk to Cayde-6 in The Lost City to pick up the Exotic quest “Wild Card,” which you not only need to complete to enter the Salvation’s Edge raid, it’ll also net you the Still Hunt Exotic. Talk to Ghost again and pick up the “Found in the Dark” and “Lost in the Light” quests, which will help fill out your Prismatic abilities even further. Follow the steps to complete both of those missions.
After you’ve helped out Caiatl and Mithrax, it’s time to jump into “Queens, part 2,” which you’ll find in The Lost City. This is another straightforward mission, so follow the objectives until you finish it.
When you land back in The Lost City, talk to Ghost one more time and he’ll give you the Dyadic Prism. Travel to the new landing zone in Sacraium in the far-right area of the map to claim your first Ergo Sum sword and gain the ability to get random rolls.
Ergo Sum weapon perks list
Ergo Sum in Destiny 2 features a diverse array of weapon perks that significantly influence its performance and playstyle. It always includes the Exotic perk Transcendent Duelist, which allows the sword to use Special ammo while reducing ammo pickups, and kills with the sword charge Transcendence bars, enhancing damage and extending the Transcendence window. The sword can roll with various frames such as Vortex, Caster, Wave Sword, and Lightweight, each affecting its handling and attack style. Additionally, Ergo Sum has blade and guard perks like Jagged Edge and Swordmaster’s Guard that boost damage output. Its elemental damage can be Arc, Solar, or Void, and it can also inherit Exotic perks from other iconic weapons, adding to its versatility. Players can pursue god rolls by combining preferred frame and Exotic perks, with the Exotic Catalyst further improving ammo management and synergy with Transcendent abilities.
Every time you get an Ergo Sum, it’ll come with a different sword frame, different blade perks, different guard perks, and one of several Exotic perks taken from other weapons – which also affects the sword’s element type.
The one perk that’s always on Ergo Sum is Transcendent Duelist, which allows the weapon to use Special ammo, but causes you to pick up less ammo when you grab a brick off the ground. It also causes kills with Ergo Sum to charge both Transcendence bars. While you’re Transcendent, Ergo Sum does more damage and killing targets lengthens your Transcendence window.
To get more Ergo Sum swords, you can either complete the new Pathfinder bounty system on The Pale Heart (you can get two swords a week doing this) or you can farm the matchmade version of the Overthrow activity, which doesn’t seem to have a limit.
As for what you can get on Ergo Sum, here’s the list of Exotic perks via Light.gg, a database site for Destiny 2:
- Wolfpack Round (Gjallarhorn): Heavy attacks grant cluster missiles to sword wielders.
- Gathering Light (Traveler’s Chosen): Stowing weapon restores ability energy based on final blows.
- Sacred Flame (Ticuu’s Divination): Heavy attacks mark targets, light attacks detonate them.
- The Perfect Fifth (Polaris Lance): Every five hits attaches a delayed explosion.
- Arc Conductor (Riskrunner): Heavy attacks surge lightning from the user.
- Stormbringer (Cloudstrike): Rapid final blows create a lightning storm.
- Unplanned Reprieve (Telesto): Heavy attacks emit delayed detonating projectiles.
- Insectoid Robot Grenades (The Colony): Final blows deploy homing robot grenades.
What secret steps unlock the power of Ergo Sum in Destiny 2
To unlock the power of Ergo Sum in Destiny 2, you must first complete The Final Shape campaign. Afterward, speak with your Ghost in the Lost City to start the “Destined Heroes” exotic quest. This quest involves several key steps:
-
Begin by tuning into a radio near your Ghost and start the “Queens, Part 1” mission, where you face a Hive Knight to claim the sword.
-
Next, complete the “Lost in the Light” and “Bound in the Dark” missions, which involve defeating enemies called Eaters of Light and Darkness, collecting orbs, and depositing them in opposite elemental platforms to break enemy shields.
-
You will encounter challenging boss fights, such as Korha the Hollow, where you must repeat the mechanic of killing Eaters of Light and Darkness to remove immunity shields and deal damage.
-
Progress through puzzle-like mechanics in the quest, including protecting allies, destroying servitors, and using elemental reflections to activate Hive Runes.
-
After defeating the final boss and completing the quest steps, return to the Old Tower and interact with the veiled statue in The Sacarium to finally receive Ergo Sum.
Ergo Sum is unique in that it can drop with random elemental affinities (Solar, Arc, Void, Stasis, or Strand) and different frames and perks, making it farmable multiple times after the initial acquisition.
This multi-step quest combines combat, puzzle-solving, and exploration, culminating in the reward of a powerful and versatile exotic sword.
What mechanics are essential to bypass the immunity shield for Ergo Sum
The essential mechanic to bypass the immunity shield for Ergo Sum in Destiny 2 involves killing specific enemies called Eaters of Light or Darkness to collect corresponding elemental orbs, then depositing these orbs on the opposite elemental platform-light or dark-to lower the shield and make the enemy vulnerable to damage. This process must be repeated to break the immunity shield during key encounters, such as boss fights like Korha the Hollow.
Additionally, in some sections, you need to kill servitors that drop arc charges, which you then deposit to spawn friendly explosive Shanks. These Shanks will destroy the shields of immune enemies called Weavers, allowing you to damage and defeat them.
Another important mechanic involves reflecting Hive enemies’ elemental bullets (void, solar, etc.) into corresponding Hive runes to dissipate barriers blocking your path.
In summary, the immunity shield is bypassed by:
-
Collecting and depositing opposite-element orbs from Eaters of Light/Darkness to lower shields.
-
Using arc charges dropped by servitors to spawn explosive Shanks that break Weaver shields.
-
Reflecting elemental Hive bullets into Hive runes to clear barriers.
Mastering these mechanics is key to progressing through the quest and ultimately obtaining Ergo Sum.
