My Epic Hunt for Destiny 2's Ultimate Weapon: The Legendary Ergo Sum!

Picture this, fellow Guardians: it's 2026, and I'm still chasing the ultimate power fantasy in the Pale Heart! Can you believe it's been over a year since The Final Shape dropped, and I'm still grinding for that perfect Ergo Sum roll? I mean, a sword that can randomly spawn Gjallarhorn wolfpack rounds or Telesto bolts with every swing? What kind of glorious madness is that?! This isn't just a weapon; it's a slot machine of destruction, and I NEEDED it. Forget saving the universe again—this was the true endgame. Let me take you on the wild, frustrating, and ultimately triumphant journey of how I became the master of the first-ever Special Exotic Sword in Destiny history.

How To Start Destined Heroes

First things first, you gotta finish the campaign. No shortcuts here, rookies! Once you've seen the credits roll, you sprint back to the Lost Tower. Your Ghost is waiting, looking all innocent. But don't be fooled—he's about to send you on a wild goose chase that will make you question your life choices. You listen to that radio, and bam! The "Destined Heroes" quest is yours. This quest is your golden ticket, your one-way pass to unlocking the rest of your Prismatic powers AND getting your grubby mitts on that sweet, sweet Sword. It's about an hour of your life you'll never get back, but trust me, it's worth it.

Complete Queens, Part I

Your first stop? A little "adventure" called Queens, Part I. Sounds fancy, right? It's basically Savathun's idea of a funhouse mirror maze, but with more Hive and elemental puzzles. The core mechanic here is pure genius: redirect damage with a Hive Sword! You pick up the sword from a slain Knight, block incoming fire, and watch as it magically empowers the matching elemental rune. It's like being a magical damage concierge.

• Arc Damage? Comes from those pesky Wizards.

• Solar Damage? Blasted from Acolytes (Lucent or otherwise).

• Void Damage? That's the Shriekers' department.

You run through this gauntlet, feeling like a wizard, until you hit the shores. And who shows up? None other than Savathun herself, just dropping in to say hi and give you more chores! Now you're throwing elemental orbs at runes. Simple, right? Wrong! Some runes have green shields. So what do you do? You grab another Hive Sword and launch a heavy attack projectile to shatter it. It's a workout, I tell you!

Complete Lost In Light & The Hollow Adventures

Alright, next up was "Lost in Light." This quest's whole purpose? To unlock the rest of your Prismatic Light subclass options. It's a fetch quest, but a necessary one. You follow your marker like a good little Guardian and complete two adventures: The Hollow: Part I & II.

The Hollow: Part I was a breeze with my buddy Mithrax. We're hacking terminals and defending my poor Ghost from Fallen swarms. Pro tip: if your Ghost takes a hit, just resummon the little guy! The real fun starts with the Light and Dark plates. You gotta hunt down Taken Captains with "Light" or "Dark" in their names, kill them for motes, and then dunk five motes on the matching plate. Rinse and repeat. The boss at the end? A total joke. I sneezed and he died.

The Hollow: Part II took us to the frozen hellscape of Europa to deal with Korha. The main gameplay loop here? Escort a suicidal Explosive Shank. This little guy has a death wish, and every enemy on the map wants to grant it. You become a bodyguard, clearing a path while this Shank toddles along. When it reaches its destination, you blow it up to clear the path. Poetic, really. The final fight with Korha involves killing Salvation Servitors for orbs, dunking orbs to spawn more Explosive Shanks, and using them to break his immunity. It's chaos, and I loved every second of it.

Complete Found In The Dark & The Home Adventures

Time to embrace the Darkness! "Found in the Dark" is the mirror to the Light quest, unlocking your Prismatic Darkness options. Another two-adventure special: Home: Part I & II.

Home: Part I is all about sabotage. You fight through a legion of Cabal to reach shield generators. Then, you wait for an Artillery Officer to spawn, kill him, grab the Artillery Antenna he drops, and plant it on a generator. Do this twice per set. Destroy all the generators, and a big, angry Colossus shows up. When he goes immune, two Subjugators spawn. Here's the kicker: you must damage them while in Transcendence! They're tanky, so bring a good Sniper or Linear Fusion Rifle. After they're down, focus fire on the Colossus until he's history.

Home: Part II is the same mission, but now with a deadly twist: Biting Cold. This debuff ticks down constantly, and when it hits zero, you're dead. Your only salvation? Standing near the fire pits scattered around the level. So now you're juggling combat, generator destruction, and not freezing to death. It's a stressful, beautiful ballet of fire and ice.

Complete Queens, Part II

Fully powered up with Light and Darkness, it was time for a final showdown in Queens, Part II. Savathun and her Lucent Brood were waiting. This mission is mostly a victory lap of add-clearing glory... until you hit the end. And what's waiting for you? A duo of Tormentors. That's right, two of those nightmare-fuel enemies at once. My heart skipped a beat! I had to whip out my best precision weapon and crowd control Supers. It was tense, but overcoming them felt incredible. The rest was just mowing down Hive with my shiny new Prismatic abilities.

Use The Dyadic Prism & Claim Your Prize!

Finally, I returned to my Ghost, exhausted but exhilarated. He handed me the Dyadic Prism, an Exotic item that clogged up my Energy weapon slot. I couldn't wait to get rid of it! I fast-traveled to the Sacrarium, started the "Hope" adventure, walked up to a mysterious veiled statue, and performed the ritual. The Prism infused with Light, and in a flash of glory... there it was. My first Ergo Sum. I held it in my hands, this beautifully random Sword. The roll? Not great. But it was MINE.

How To Farm Ergo Sum: The Never-Ending Grind

But one Ergo Sum is never enough, is it? Not when every part of it is random! The real grind began. In 2026, the farm is still alive and well. Here's how you get more:

Source	Drop Chance	Weekly Cap?	Notes
Pathfinder Rewards	Guaranteed per reward set	Yes (2 per week)	The most reliable way. Complete those Pathfinder boards!
Overthrow Activity	Random Chance	No known cap	The classic mindless farm. Put on a podcast and go to town.

I've lost count of the hours I've spent in Overthrow. The thrill of seeing that yellow engram drop, the agony of getting another roll with a useless trait... It's the Destiny loop I both love and hate. Will I ever get the God Roll with the perfect frame and an Exotic perk that spawns Gjallarhorn rounds? Who knows! But the chase is everything. This weapon embodies what makes Destiny great in 2026: endless pursuit, unpredictable power, and the sheer joy of swinging a sword that might do literally anything. So, what are you waiting for, Guardian? Get out there and start your own epic hunt! Isn't it time you forged your own legend?
