If you're hunting the Mythic Prankster Nightmare Sigil, you already know the worst part isn't the fights—it's the downtime. So I stopped treating it like a random drop and started running a loop that keeps itself alive. If you're short on supplies early on, grabbing a bit of cheap diablo 4 gear to smooth out your clears can help, but the real win is building a rotation that keeps your materials coming back while you roll more sigils.

Get Your Prep Right

Don't start this half-broke. You want a real stash of Living Steel first—around 200 is the point where the loop stops feeling like work and starts feeling like momentum. You're also gonna want your outdoor boss essences set correctly, because messing that up quietly tanks your results. Slot a Level 5 Essence of Sin into the Purified slot and a Level 5 Essence of Hellfire into the Corrupted slot, then check it again before you leave town.

Grigo First, Then Duriel

Start at Grigo on Torment IV and burn Living Steel with a purpose: you're farming Stygian Stones and stacking Shards of Agony. While you're in there, watch for Bile spawns. People ignore them, then later wonder why the next step feels slow—those Betrayer's Husks matter. Once you've got enough to move, go to Duriel and keep one thing in mind: Corrupted Horns have an inventory cap of 20, and when you hit it, they just stop dropping. The easy workaround is to leave Horns on the ground while you spend down your Shards, then do one clean sweep and pick them up after.

The Asmodan Chest Loop

Take your Horns and Eyes to the outdoor Asmodan event south of Zorbins. This is where the loop turns from "farm" into "engine." Open the Duriel and Bile chests and you'll notice the materials coming back—Living Steel and Exquisite Blood show up often enough that you're not running back to Helltides every hour. The big reason you're here, though, is sigil volume. Those chests can drop Nightmare Sigils at a really solid rate, and more rolls is the whole point.

Loot Discipline and the Backup Chain

When sigils hit the ground, don't mash pickup like you're clearing trash. Step back, grab them one at a time, and actually look at the visual effect so you don't lose track or accidentally junk something valuable. If it's not the one you want, take the extras to the Occultist, salvage, and use the powder to craft more—keep the cycle moving. And if you ever dip on materials, the fix is built in: use the Exquisite Blood from the chests to run Lord Zir, turn that into Dolls, push Andariel, then bring her Corrupted Claws right back into the same event loop.
