U4GM Guide to Diablo 4 Hellwyrm Rush

Diablo 4 Season 15, Season of Hell's Legacy, arrives on September 15, 2026, with Patch 3.2.1. If you want a quick start, Kurast Undercity deserves attention from the moment it becomes available. The Jade Epiphany node changes the whole rhythm of the run, turning Attunement gains into experience bursts. That means less time fighting random packs and more time moving with purpose. A small stock of D4 items can also make the early journey smoother, especially when your build still lacks its key pieces.

Build Around Jade Epiphany

Once your character reaches level 25, start working towards Jade Epiphany through the War Plans Command Table. Before the node is active, rush through Kurast Undercity and head straight for the finish. You are not there to clear every room. You are there to complete runs and collect the points needed for the upgrade.

1. Enter Kurast Undercity and move past ordinary enemies whenever the path is safe.

2. Raise Attunement as quickly as possible, since each rank creates new experience orbs.

3. Pick up the orbs yourself; pets do not collect this particular reward automatically.

4. At Rank 4, reach the boss room, finish the encounter, and restart the activity.

Why the Undercity Route Feels So Fast

Jade Epiphany rewards movement and awareness rather than full dungeon clearing. You will soon notice that stopping for every group slows the run more than it helps. Watch the Attunement progress, grab each orb before moving on, and keep your route simple. The fourth rank is the key checkpoint. Once it appears, there is little reason to wander through side rooms or chase extra targets.

Switch to Hellwyrms When the Map Lines Up

Helltides remain the strongest option when the War Plans Command Table offers several suitable entries. Look for the Writhe and Rot keystone, then raise the Threat Level until the final stage. When Hellwyrms appear, follow them and defeat the Plague Maggot Young they release. Avoid ordinary enemies at this point. Filling the meter too far can summon a champion and interrupt the worm cycle. You can also change to Penitent just before opening chests or turning in Aberrant Cinders, gaining the higher reward without spending the whole run in tougher fights.

Pick a Route That Fits Your Evening

The fastest players can combine Hellwyrm runs with Kurast resets and reach level 70 in about an hour. That is not the only sensible choice, though. Helltides, Infernal Hordes, Tree of Whispers tasks, and Undercity runs together provide materials, Legacy Uniques, and resources for later Masterworking and Mythic crafting. As a professional platform for conveniently buying game currency or items, U4GM can help when you need extra support, and you can purchase u4gm D4 items to round out your build before tackling Torment and the returning Prime Evils.
