U4GM Guide to Diablo 4 Hellwyrm Rush Leveling

Andrew736

Season 15, known as Season of Hell's Legacy, changes the opening hours of Diablo 4 quite a bit. With Patch 3.2.1 arriving on September 15, 2026, players will have new tools to work with, including Soul Splinters and the War Plans Command Table. Diablo, Baal, and Mephisto also return, but most players will want to reach level 70 before facing that wider endgame. With a smart route and a few useful D4 items, that climb can take close to an hour rather than an entire evening.

Start With the War Plans Table

As soon as your new character enters the world, interact with the Horadric Cube. It grants an early level and opens Tyrael's introduction to the War Plans Command Table. Keep refreshing the available plans until Helltide activities appear. You are looking for the Writhe and Rot keystone. It changes the event in a very specific way: Hellwyrms arrive and release Plague Maggot Young instead of joining the fight themselves. Those maggots drop large experience orbs, so the real job is following the worms, not clearing every creature nearby.

Route	Best stage	Main objective
Hellwyrm Rush	Level 1 onward	Raise Threat Level, then collect maggot orbs
Undercity Rush	Level 25 onward	Reach Attunement Rank 4 quickly
Mixed activities	Any stage	Build levels, materials, and gear together

Keep the Helltide Loop Clean

In Helltide, push the Threat Level towards its last section. Once Hellwyrms start appearing, stop attacking ordinary enemies. A full meter brings in a champion and clears the progress, which interrupts the useful spawn pattern. Stay close to the worms and pick up every orb yourself. Before opening chests or handing in Aberrant Cinders, change the difficulty to Penitent for the reward multiplier, then switch back if the fights become awkward. Maps from experienced players can help you find repeatable routes through Kehjistan and Scosglen.

Use the Undercity After Level 25

At level 25, Kurast Undercity becomes a strong alternative. First, earn enough War Plan points to unlock Jade Epiphany. Until then, run straight towards the end and ignore side packs. Once the node is active, each Attunement increase creates experience orbs near your character. Pets do not gather these drops, so manual pickup matters. A clean run looks like this.

Enter the Undercity and move towards objectives.
Reach Attunement Rank 4 without wasting time on side fights.
Collect the orbs after every rank increase.
Defeat the boss, leave, and start another run.

Choose Speed or Long-Term Value

The mixed route suits players who dislike repeating one activity. Rotate through Helltides, Undercity runs, Infernal Hordes, and Tree of Whispers tasks. It may take around ninety minutes to reach level 70, but the character gains crafting materials, Legacy Uniques, and supplies for Masterworking and Mythic crafting along the way. That extra preparation can make the first Torment tiers feel far less harsh.

What to Have Ready

Before starting, clear your inventory, prepare movement skills, and decide which route fits your build. Fast travel saves more time than chasing a small amount of extra experience. The Hellwyrm route is best for pure speed, while Undercity offers a repeatable mid-game rhythm. A mixed schedule feels more relaxed and leaves you better prepared for the Prime Evils, especially when you use buy cheap D4 items to fill an awkward gear gap before pushing higher difficulty.
