In the neon-drenched, post-apocalyptic alleys of Zenless Zone Zero, every Proxy’s journey is defined by their Inter-Knot Level—a badge of honor that marks overall progression and opens the floodgates to the game’s deepest content. Reaching Inter-Knot Level 20 is the first major litmus test; it’s where the training wheels come off and the real party starts. For beginners, this climb can feel like pushing a boulder up Mount Olympus, but fear not. With the right strategy, you’ll be hitting that milestone so fast it’ll make your head spin. This guide lays out the quickest routes, top-shelf tips, and a few pro-tricks to turbocharge your Inter-Knot Credits and unlock the fabled Rank-up Trial without breaking a sweat.
Inter-Knot Level is the account-level system that mirrors Genshin Impact’s Adventure Rank and Honkai: Star Rail’s Trailblaze Level. As of 2026, HoYoverse has polished this progression loop to a mirror shine, but the climb to Level 20 still demands a solid grind. The payoff, however, is nothing to sneeze at. Once you plant your flag at Level 20, the first Rank-up Trial becomes available—a challenging quest that, when cleared, raises the level cap of your Agents, W-Engines, and Bangboos from 20 to 30. It also toughens up Ethereal enemies and ramps up Commission difficulty, meaning richer rewards across the board. It’s a classic risk-reward tango that every seasoned Proxy learns to love.
To even knock on the door of the Rank-up Trial, you’ll need three things: Inter-Knot Level 20, completion of Main Story Chapter 1 – Intermission, and 40 Observation Data collected. Miss any of these, and you’ll be left twiddling your thumbs while your friends dive into higher-level Commissions. But the real currency that oils the gears of your Inter-Knot climb is Inter-Knot Credits. Getting them by the bucketload is the name of the game, and here’s where the rubber meets the road.
Commissions are the bread and butter of any Inter-Knot leveling strategy. These are your main quests, combat stages, and exploration missions, and they shower you with anywhere from a handful to a whopping 500 Inter-Knot Credits per clear. The golden rule is to prioritize Story Commissions first—think of them as the spine of your progress. Once the main narrative is caught up, pivot to Combat and Explore Commissions to keep the Credits flowing. It’s a straight shot to Level 20 if you follow this order. Let the side stuff simmer while the story cooks, and you’ll be amazed at how fast the numbers tick upward.
If Commissions are the slow-roasted main course, Errands are the quick-hit snacks that keep you fueled every single day. These are bite-sized tasks—six easy quests plus one Weekly Custom Schedule—that refresh at 4 a.m. GMT+8 like clockwork. Each Errand challenge doles out 150 Inter-Knot Credits, bringing the daily total to a juicy 600 credits. Do them religiously, and you’ll rack up enough Credits to make the Level 20 climb feel like a downhill cruise. It’s the kind of low-hanging fruit that separates the casual weekend warriors from the front-of-the-pack Proxies.
For those who like a little extra spice, Primer missions are the unsung heroes of fast leveling. These are tougher than Errands but come loaded with treasure—not only 100 Inter-Knot Credits per challenge, but also Polychromes and Master Tapes. While 100 Credits might sound like small potatoes, the cumulative effect is huge when you’re already juggling Commissions and Errands. Think of Primer missions as the cherry on top of your daily routine. They push your resource pool and your Inter-Knot Level forward in one fell swoop, making them a no-brainer for anyone serious about hitting Rank-up milestones.
A spoonful of efficiency helps the grind go down. Mixing all three activity types—Story Commissions, daily Errands, and tough-as-nails Primer missions—creates a leveling rhythm that’s smooth like butter. Don’t sleep on the Observation Data either; those glowing collectibles tied to exploration and achievements are mandatory for the Rank-up Trial. Scoop them up as you roam the Hollows, and you’ll thank yourself later. It’s also worth noting that as you approach Level 20, the Inter-Knot Credit requirements per level creep up, but by then you’ll be a well-oiled machine, marching toward your goal with the confidence of a Proxy who knows the ropes.
In the current landscape of 2026, the community has honed these strategies to an art form. New Proxies can go from zero to hero in a matter of days, while veterans still grind Errands for that sweet dopamine hit of efficient progress. The beauty of the system is its clarity: do the story, knock out your dailies, challenge yourself with Primers, and let the game reward your hustle. Reaching Inter-Knot Level 20 isn’t just a checkbox—it’s your all-access pass to a world of heightened challenge, stronger foes, and loot that makes all the grind worthwhile. So grab your gear, rally your squad, and show the Sixth Street who’s boss. The Proxy network is waiting for you to rise.
