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 to reach endgame in a single sitting. Others would rather keep the journey varied and avoid repeating the same activity for hours. Your early choices matter, especially when you are deciding which skills to unlock, where to spend seasonal progress, and how much gear to replace along the way. Even a few useful Diablo 4 Items can make the opening levels feel much less awkward, but the route itself still does most of the work.

Hellworms Push Experience at a Remarkable Pace

Hellworms are the high-speed option for players who already know the seasonal systems and do not mind a slightly fussy routine. The idea is simple: build Helltide threat, move through likely spawn areas, collect the experience globes, and repeat. From level 1 to 24, put your attention on Helltide objectives in the War Plans system. The available choices are narrower at this stage, so it is easier to steer progress towards the bonuses you need. Once Rift and Rot is active, the farming loop becomes much stronger. You are not trying to clear every monster. You are building threat, watching for the worm, and keeping the route moving.

Keep Your Character Strong Enough to Move

Fast experience creates a problem that is easy to overlook. Your level can rise faster than your equipment improves. One minute your weapon feels fine; a few level-ups later, basic enemies take far too long to kill. Do not pour rare materials into gear that will be replaced almost immediately. Instead, visit town often and check the vendors. A fresh weapon with better damage can be enough to keep the whole run smooth. The same rule applies to difficulty. Higher difficulty sounds appealing, but it is only worthwhile when you can clear without constant deaths or long fights. If the pace drops, step down, regain momentum, and move up again when your build catches up.

Undercity Delivers a Smoother Grind

The Undercity suits players who want a reliable routine rather than a hectic Helltide circuit. It opens at level 25, and the Jade Epiphany node in War Plans should be one of your next useful targets. Each Attunement rank adds experience globes, with the rewards improving as you move from the first rank towards Attunement 4. There is no need to search every corner of the activity. Push towards the boss, finish the run, collect the reward, and start again. This approach feels much easier to manage when you are playing after work or levelling a second character. The gains are steady, and the route asks less from you than constant threat control.

War Plans Add Variety to the Journey

War Plans are the better fit when you want progress without turning the whole season into one repeated farming loop. Helltides can provide strong experience and help you work towards Hellworm bonuses. The Pit is useful when your build is already comfortable there, while the Undercity gives you a dependable change of pace. Try not to force every activity into the rotation. Hordes, for example, may take longer than expected for the experience they provide during early levelling. Pick tasks that line up with your current strength, then adjust as your character develops. You can start with Helltides, switch to Hellworms for a burst of progress, and settle into the Undercity when you want something calmer.

Final Thoughts

There is no single route that feels perfect for every player. Hellworms can take you towards level 70 at an impressive speed, though the method rewards preparation and close attention. The Undercity is more forgiving and easier to repeat, especially after level 25. War Plans offer the widest mix of activities and help your character prepare for later content while you level. Keep your weapon damage current, avoid wasting materials on short-lived upgrades, and spend gold with a purpose. Having enough D4 Gold for sale available can help cover vendor purchases and repairs when your gear starts falling behind. A good levelling route should leave you with more than level 70: it should give you a working build and enough momentum to step into the endgame.
