Destiny 2 is weird. Honestly, it’s a game that loves to explain things through cryptic lore entries and then smack you in the face with a mechanic that feels like doing taxes while being shot at by space aliens. If you’ve been trying to untangle founts of light and darkness, you’re probably neck-deep in the Root of Nightmares raid or messing around with the seasonal activities that utilize the duality of paracausal energy. It’s not just about standing in a circle. It is about timing. It’s about understanding how the game "reads" your character’s state.
Most people fail this because they treat it like a standard capture point. It isn't.
What’s Actually Happening When You Connect the Founts?
Think of the founts as electrical circuits. You have a source and a receiver. To untangle founts of light and darkness, you basically have to act as the copper wire. You grab a buff from a "node" (that’s the glowing sphere) and carry it to the next one in the sequence. If you’re doing the Light side, you’re looking for that bright, almost pearlescent white glow. Darkness? That’s the jagged, orange-and-black resonance.
The "untangling" part comes in when the game starts overlapping these paths. In the Root of Nightmares raid—specifically during the Cataclysm and Scission encounters—you can’t just run around aimlessly. If you have the "Field of Light" buff and you accidentally step into the Darkness aura while someone is trying to activate it, you might reset the whole chain. Or worse, you wipe the team. It’s a mess.
You’ve got to be precise.
The Mechanical Breakdown: Buffs and Tethers
When you stand in the aura of a fount and shoot the central node, you get a 20-second timer. This is your window. You have to find the next inactive node in the chain—it’ll be a dull version of the one you just left—and shoot it while standing inside its radius.
Wait. Don't just shoot and run.

You need to see the line connect. If you’re trying to untangle founts of light and darkness in the Scission encounter, the game forces you to cross the chasm. This is where the difficulty spikes. You have the Light team on one side and the Darkness team on the other. But the nodes they need to hit are on the opposite sides. You’re literally criss-crossing paths in mid-air.
If you don't communicate, you’ll "tangle" the founts. This happens when two people with opposite buffs stand in the same aura at the same time. The game gets confused, the node locks out, and you lose precious seconds on your wipe timer.
Why Most Teams Wipe on This
Chaos. That’s the short answer.
In the heat of a Master-level run, everything is exploding. You’ve got Tormentors jumping on your head and Barrier Champions turning you into Swiss cheese. People panic. They forget to check if their teammate is already in the node.
To effectively untangle founts of light and darkness, you need a "call and response" system.
"Light node 2 is ready."
"Don't shoot yet, I'm still clearing ads."
"Okay, shooting now."
If you shoot the node while a teammate who doesn't have the buff is inside the circle, they don't get the buff, and the node might go into a cooldown state. It’s annoying. It’s specifically designed to punish players who try to solo-carry without looking at what their five other friends are doing.

The Secret to Speed: The "Shotgun" Method
There is a way to make this faster. Some high-level players call it "bumping." Basically, you have one person dedicated to being the "buffer" who stays near the start, and runners who just move from point A to point B.
But honestly? Just move.
The biggest time-waster when you untangle founts of light and darkness is jumping. If you're a Warlock, use Icarus Dash. If you're a Titan, use Lion Rampants or a well-timed shoulder charge. If you're a Hunter... well, try not to miss the platform. The faster you get to the next node, the more time you have to deal with the actual threats, like the bosses that are usually screaming at you from across the arena.
Variations in Other Activities
While the Root of Nightmares is the primary place you’ll deal with this, the concept of "untangling" light and dark shows up elsewhere. Remember the Prophecy dungeon? Or the way the Witness's influence manifests in the Pale Heart? It’s all the same logic.
You’re balancing two opposing forces.
In the Pale Heart, "untangling" often involves the Mote system. You collect Light motes from enemies killed with abilities and Dark motes from... well, just about anything else. You have to dunk them in specific sequences to unlock chests or progress through the "Overthrow" events. It’s a simplified version of the raid mechanic, but the thematic core is identical: parity.

Common Misconceptions About Paracausal Founts
One thing I see people get wrong constantly is the idea that you can "overwrite" a buff. You can't. If you have "Flux of Darkness" and you try to grab "Field of Light," you won't just switch. Usually, the game will prevent you from picking up the second one until the first one expires, or it will just kill you.
Also, the nodes have a "return" path.
If you take too long to untangle founts of light and darkness, the nodes will start to recede. It’s like a rubber band. You pull it out, but if you don't hook it onto the next peg, it snaps back to the start. This is why "staying on rhythm" is the most important piece of advice any raid lead can give you.
Expert Tips for Flawless Execution
- Check your feet. If you see a swirling floor effect that matches the color of your buff, you're in the right place. If it’s the opposite color, get out of there immediately.
- Listen for the audio cue. There is a very specific "chime" when a node is successfully activated. If you don't hear it, the connection didn't happen.
- Use the environment. In many encounters, there are physical barriers that only drop once you've untangled a specific set of founts. Use these as your markers. If the door isn't open, you missed a node.
- Don't kill the "Psions" too early. In some encounters, certain enemies trigger the next phase of the fount sequence. If you nuke everything instantly, you might find yourself waiting for a spawn while your buff timer ticks down to zero.
Moving Toward the Final Shape
As we push further into the post-Final Shape era of Destiny 2, these mechanics are becoming more integrated into the "Prismatic" subclass fantasy. We are no longer just using Light or just using Darkness. We are the bridge.
The act of trying to untangle founts of light and darkness is a metaphor for what the Guardian is doing on a cosmic scale. We are taking two chaotic, opposing universal forces and weaving them into something usable. Something powerful.
If you’re struggling with the mechanics, go into a solo instance of the first raid encounter. Don't even try to beat it. Just practice grabbing the buff and hitting the nodes. Get a feel for the distance. Watch how the "tether" line behaves when you move behind a pillar. Once you understand the "physics" of the founts, the rest of the game becomes significantly easier.
Actionable Steps to Improve Your Runs
- Audit your movement: Switch to high-mobility gear specifically for these sections. Stompees, Transversive Steps, or Dunemarchers are non-negotiable for runners.
- Clear the "Interruption" enemies first: In the Scission encounter, Centurions will spawn that can actually block the founts from working. Kill them the second they appear.
- Set a "Node Order": Assign numbers to the nodes (1 through 6). Don't use vague descriptions like "the one by the rock." There are too many rocks.
- Watch the "Wipe" timer: If you see the screen start to glow bright white or deep red, you’ve run out of time. At that point, stop trying to connect nodes and just look for a "safe" aura if the mechanic provides one.
- Practice "Prismatic" synergy: If you're using the new subclasses, remember that your Transcendence state can often bypass some of the cooldown frustrations, though it won't let you cheat the node mechanics themselves.
Mastering this isn't about having the best aim or the highest DPS. It's about being the most organized person in the room. When you can untangle founts of light and darkness with your eyes closed, you stop being a liability and start being the person who carries the team to the finish line.
