I've played a lot of Diablo 4 seasons, and most of the time the "new" stuff feels like another lap around the same track. This time, though, the uber secret boss actually made me stop and pay attention. It starts like a rumor you heard in voice chat and didn't totally believe. Then you chase it anyway, because why not. If you're already stockpiling Diablo 4 Items and tinkering with your build, this hunt slots right in and feels way more alive than a standard checklist grind.

Getting The Four Purified Pieces

You can't just stroll up and press a button. The portal needs four specific Purified items: the Purified Eye of Balile, the Horn of Duriel, the Tongue of Asodan, and Purified Andariel. The annoying part is how easy it is to think you've got everything, then realize you're short one piece and you're standing there like an idiot. Do yourself a favor and party up. In a group, one person can cover the missing component and still open the portal, so nobody's run is wasted. Each item is tied to content around that lesser evil, so you're basically doing targeted farming instead of blind praying.

Altars, Placement, And That "Oh No" Moment

Once you've got the set, you'll be running around the expansion zones looking for the altars. They're not all in one neat spot, either: Anguish, Lies, Pain, and Sin. Drop the items where they belong, and the tone shifts fast. The screen gets darker, and it suddenly feels like you've stepped into something you weren't meant to find. Then the portal pops and you're in, with three bosses waiting—Andariel, Balile, and Asodan—stacked together like the game's daring you to blink.

How The Fight Actually Plays

This isn't one of those fights where you can half-watch a video on your second monitor. Meteors come down, circles fill the floor, and the space you thought you had disappears. It's messy, but not unfair. If your build is tanky and you're used to soaking damage, you might brute force it, sure. Most players I've seen get more consistent clears by moving with purpose: step out, re-engage, don't chase damage into a bad spot. Also, don't enter with a packed inventory. You'll regret it when loot starts piling up and you're fumbling in the middle of chaos.

Loot That Feels Like A Payoff

The reason people keep talking about this encounter is simple: it pays. My first clear felt wild—guaranteed Spark, two Mythics, and the Crest of Exile mount on top, plus other endgame crafting bits that actually matter. It scratched that old-school itch, like stumbling into something secret and getting rewarded instead of getting trolled. If you're short on time or trying to speed up your gearing for the next attempts, it's not weird to lean on trading and services; plenty of folks use U4GM to grab currency or items faster so they can focus on the fight instead of another long farm loop.
