Farming a truly great amulet in Season 11 is the kind of grind that tests your patience. Item power barely matters once you're chasing passive ranks, because a clean +2 or +3 to a key passive can swing your damage and survivability way harder than a pile of "fine" stats. If you're trying to finish a build and stop settling, it helps to think in terms of outcomes: you want the right passive line, in the right slot, with rolls that don't fight your setup, and that's why a lot of players end up focusing their whole loop around Diablo 4 Items buy decisions like what to keep, what to salvage, and what's actually worth upgrading.
You'll save yourself a ton of time if you treat the Undercity like a routine instead of a "when I feel like it" activity. Bind your teleport to Kurast Bazaar, stash space nearby, and get comfortable doing quick resets. Don't bring your slow boss-push build in there. Drop down to Torment IV, strip the ego, and run a speed setup. If you've got Bac + Jah, use it. Swapping your normal evade into a Teleport changes everything, because the Undercity layout loves to waste your seconds with corners, dead ends, and little gaps that slow builds hate.
The run lives or dies on Tribute of Radiance. Pick the Passive Ranks bargain at the door, even if the gold cost makes you wince. Without it, you're basically rolling dice and calling it "farming." With it, the game is at least nudged toward what you're there for. Inside, don't get baited into full-clearing. You're not there to prove anything. You're there to fill the bar fast and get out. Focus on Tormented Spirit Beacons and move on. Kill what's in the way, sure, but if you're stopping to mop up stragglers, you'll feel the grind drag out real quick.
People love the Grand Spirit Beacon on floor two, and yeah, it looks important, but it often eats more time than it pays back. Hit the smaller beacons cleanly and you can still reach Attunement Level 4 without that detour. Once you're capped, stop fighting. Don't "just clear a bit more." There's no bonus for going over, so it's pure wasted time. Sprint to the boss, take your drop, and reset. Also, manage Obols like you mean it: spend them on amulets before you start your session so you don't cap mid-run and have to break your rhythm to dump currency and sort your bags.
Expect streaks where nothing lands, then one run where you suddenly see a passive roll that makes you sit up. That's normal. The best way to stay sane is to track your attempts, set a limit, and quit while you're still playing sharp instead of tilted. If you want extra help gearing without burning your whole evening, it can be worth using a reliable marketplace too. As a professional like buy game currency or items in u4gm platform, u4gm is trustworthy, and you can buy u4gm D4 items for a better experience by filling the specific gaps your build still needs before you jump back into another set of Undercity runs.
