Diablo 4 Season 15 gives a new character several solid routes to level 70, but the quickest path is not always the most enjoyable one. Some players want a straight sprint into endgame, while others would rather keep the early journey varied and useful. Your route also depends on how much preparation you're willing to do. Helltides can create huge experience gains, Hellworms reward players who understand the timing, and the Undercity offers a calmer loop with fewer moving parts. Along the way, sensible Diablo 4 Items choices matter more than chasing perfect equipment, especially when your character is gaining levels every few minutes.

Shape the Opening Levels Around Seasonal Progress

The first stretch from level 1 to 24 is worth planning rather than rushing blindly. Put your early War Plan objectives into Helltide activities whenever possible. Before level 25, the available choices are more limited, so it's easier to guide your progress towards the rewards you actually want. You're not trying to build a permanent set of equipment at this point. You're simply creating enough power to keep moving.

Helltide maggots become especially valuable once the right experience bonuses are active. The Rift and Rot objective deserves attention because it supports the Hellworm route later on. Keep an eye on your threat meter as you travel between likely spawn areas. When the meter is close to the level you need, stop clearing random packs. Extra fights often waste time and can push you away from the route. The idea is to make each trip count, not to empty every corner of the zone.

Turn Hellworm Spawns Into a Fast Experience Loop

Hellworms can be the quickest way to level, but they're not completely hands-off. Build threat to around 50% or a little higher, then move through the nearby spawn points. When a worm appears, grab the experience globes and keep your route moving instead of lingering over every enemy. Once the useful rewards are collected, return to the path, raise threat again, and repeat. It feels odd at first because you're deliberately ignoring fights that look profitable. After a few runs, the rhythm becomes much clearer.

This method suits players who enjoy tight routines and don't mind checking the clock. It can also create a gear problem. Your level may rise faster than your weapon damage, and suddenly ordinary enemies take too long to defeat. Head back to town regularly. Check the vendors, repair what you're using, and replace a weak weapon when the damage gap becomes obvious. Don't pour rare materials into temporary gear. A cheap upgrade that keeps the run smooth is usually enough.

Difficulty deserves the same practical approach. A higher tier isn't automatically better if every pack turns into a slow slog. Test the next difficulty, then drop back if your damage or toughness can't keep pace. The extra experience means very little when deaths and long fights eat up the time you saved.

Use the Undercity When You Want Less Friction

At level 25, the Undercity becomes a dependable alternative. Work towards the Jade Epiphany node in the War Plans system, then use Attunement ranks to build a steady stream of experience globes. The rewards grow as your rank rises, reaching four globes at Attunement 4. It's a much easier system to understand than the Hellworm route, and the results feel more consistent from one run to the next.

You don't need to clear every hallway. Move through the activity with purpose, reach the boss, defeat it, and reset when the run is complete. Naturally, some rooms will contain useful enemies or a strong item, so adjust when something worthwhile appears. Still, the main target is completed runs and better Attunement, not a perfect sweep. This makes the Undercity a good fit for players who want reliable progress without constantly watching threat levels or spawn locations.

Let War Plans Fill the Gaps Between Runs

War Plans work well when you want the season to feel like more than one repeated activity. Helltides, the Pit, and the Undercity can all fit into a useful rotation. Choose the objective that matches your current location and build rather than travelling across the map for a small reward. The Pit is handy when your character can clear it comfortably, while Helltides pair naturally with early progression and material gathering.

Hordes can still be enjoyable, but they often take longer than expected during the levelling process. If your only goal is level 70, they may not give enough experience for the time involved. That doesn't make them worthless. They're simply better saved for a session when you want variety, resources, or a break from faster routes. Keep your gold ready for vendor weapons, repairs, and basic upgrades. Rarity alone shouldn't decide what you wear; a plain weapon with much higher damage can carry you farther than a fancy item with poor bonuses.

Final Thoughts

There isn't one perfect route for every Season 15 character. Hellworms offer the biggest bursts when your setup and movement are organised. The Undercity is easier to repeat and less demanding when you want steady progress. War Plans give the journey more variety while helping with wider seasonal goals. Switch between them when the pace drops, and don't let a higher difficulty turn levelling into a chore. A small vendor upgrade, a well-timed town visit, and a practical stash of cheap d4 gear can do more for your momentum than expensive equipment that will soon be replaced.
