Once you start chasing Mythic Uniques in Diablo IV, the real issue shows up fast. It's not just low drop rates. It's the pile of runes you don't need and the one rune you never seem to see. Your stash fills up with repeats, your plans stall, and the whole thing starts to feel less like progress and more like punishment. That's why a lot of players who are already managing materials like Diablo 4 Gold On Season 12 SC stop relying on random luck and build a proper farming loop instead.


Make the Undercity your main source
If you want more control, the Undercity has to be the centre of your grind. Not because it's glamorous. Because it spits out volume. And volume matters more than people admit. The more runs you finish, the more runes you pull, and the more chances you get to turn bad drops into useful ones. You can't do that on a slow build, though. If you're jogging from pack to pack and taking ages on elites, you're wasting the best part of the method. Mobility skills, fast screen clears, quick resets. That's what keeps the engine running. You'll notice pretty quickly that speed farming beats "careful" farming by a mile when your goal is rune conversion, not sightseeing.


Use junk runes as material, not clutter
A lot of players still treat duplicate runes like dead drops. They're not. They're ingredients. The Jeweler is where a bad session starts paying you back. Instead of crafting one piece at a time and hoping for a miracle, save your lower-tier runes and do it in bulk. That's the trick. One small craft feels random. Fifty crafts feels like pressure on the system. You're not guaranteed the exact rune you want right away, sure, but you are steadily dragging value upward. It's basically your safety net against rotten luck. Before you burn anything valuable, though, check every recipe first. People rush this part all the time, then realise they just spent a key rune they were meant to hold. That mistake hurts more than one bad drop ever will.


Keep Tributes flowing with Whispers
The weak point in the whole strategy is Tribute supply. No Tributes, no Undercity loop. That's why Whisper farming isn't optional. It's support work, but it matters. Knock out Whisper objectives, stack the caches, and don't crack them open the second they land in your inventory. There's a real advantage in saving a bunch and opening them in one go. You get a cleaner burst of Tributes of Harmony, plus more crafting resources to keep the cycle alive. It also helps you stay focused. Too many players drift off chasing side distractions, full-clearing maps, or veering after every goblin they see. If it slows the run, leave it. And once your build can survive Torment 4 without turning every fight into a slog, move up. The better drop quality makes the whole process less painful.


Play for efficiency, not for noise
The late game gets much easier when you stop treating every activity as equal. It isn't. Some things look rewarding and secretly waste your time. The smart route is simple: Whisper objectives for Tributes, Undercity clears for rune volume, Jeweler crafting for upward conversion, then strict protection of the runes tied to your Mythic recipe. That loop won't make the game feel lucky, but it will make it feel manageable, and that's a huge difference when you're deep into the grind.
