Every player worth their Waveplates knows that a well-built Jianxin can turn the tide in Wuthering Waves faster than you can say "Roaring Rock Fist." This deceptively gentle fist-fighter moonlights as both a sub-DPS buffer and a surprisingly sturdy support, which is why she’s been holding court in the high-tier lists for a while now. But pampering her to Level 90 isn't a walk in the park—it’s a full-on material heist. So, grab your map and your sense of humor, because we’re about to raid Tiger’s Maw, bully a giant monkey, and shake down some Howlers for their lunch money.

Before you even think about punching the Feilian Beringal, you need to know what you’re getting into. Here’s the complete grocery list for a maxed-out Jianxin, broken down by ranking tier. Keep in mind, these numbers don't lie—and neither does the 170,000 Shell Credit bill at the end. Better start saving.

Level Threshold	Howler Cores	Roaring Rock Fist	Lanternberry	Shell Credits
20	4x LF Howler Core	–	–	5,000
40	4x MF Howler Core	3x	4x	10,000
50	8x MF Howler Core	6x	8x	15,000
60	4x HF Howler Core	9x	12x	20,000
70	8x HF Howler Core	12x	16x	40,000
80	4x FF Howler Core	16x	20x	80,000

Totals? A cool 170,000 Shell Credits, 60 Lanternberries, 46 Roaring Rock Fists, and a messy assortment of Howler Cores (8 LF, 8 MF, 12 HF, 4 FF). That’s enough to make a supply-chain manager weep. But fear not—each material has its own little personality and favorite hiding spots.

Lanternberries: The Glow-in-the-Dark Tricksters

Let’s start with the Lanternberry, a fruit so cheeky it only grows inside dark caves, as if it's daring you to trip over a stalagmite while you pick it. Jianxin apparently loves the stuff—maybe it’s the slight luminescence or the fact that it goes wonderfully with fist-fighting. Whatever the reason, you’ll need 60 of them.

These glowing bad boys grow exclusively in the labyrinthine caves of Tiger’s Maw, that rugged area south of Jinzhou. If you enjoy spelunking with a purpose, this is your jam. Each cave system holds a handful of bushes, and the respawn timer means you’ll be back every couple of days like a berry-addicted hermit. The alternative? Put on your merchant pants and visit the Shifang Pharmacy in Jinzhou. The pharmacist there keeps a rotating stock of up to 15 Lanternberries per week—useful when you’re just six short and the next cave run would eat into your dinnertime. You know the feeling: “Just one more plant,” and suddenly it’s 3 a.m.

A pro-tip from the veterans: don’t sleep on the pharmacy. It might feel like cheating, but in a world where resources respawn on their own sweet schedule, the shop is your best friend. Just remember to drop by every Monday, cap in hand, and say, “A dozen Lanternberries, please, and make it snappy!”

Howler Cores: From Pupper Choppers to Big Boy Chews

Now, on to the Howler Cores. These things are the universal “I dropped this, please pick it up” token of any TD that howls, growls, or otherwise makes a nuisance of itself. Jianxin needs a surprising variety—Low Frequency, Mid Frequency, High Frequency, and the elusive Full Frequency. They sound like radio stations, but they’re actually the crystallized remains of your enemies’ poor life choices.

Farming Howler Cores is refreshingly straightforward: find Howler TDs, defeat Howler TDs, collect their tears. Early rarities (LF and MF) practically rain from the sky in the first few zones, but if you’re feeling lazy, Uncle Wei at the Weapon’s Shop in Jinzhou sells a limited batch of LF and MF cores. It’s like buying pre-ground coffee—sure, you could grind it yourself, but sometimes you just want the caffeine.

For bulk farming, however, nothing beats Forgery Challenges. They’re designed to drown you in core materials, and you’ll often walk away with more than you know what to do with—until Jianxin asks for 12 HF cores, at which point your smug inventory suddenly feels inadequate. To bridge that gap, pay occasional visits to the Synthesizer in Jinzhou. Combine three lower-tier cores to craft one higher-tier core. It’s the circle of life, Wuthering Waves style. Just be careful not to accidentally craft an FF core when you still need HFs; the Synthesizer doesn’t have an "undo" button, and you’ll be stuck with an expensive paperweight until your next boss fight.

Roaring Rock Fist: Punching the Punching Bag

The star of the show—and the material that will make or break your Jianxin dreams—is the Roaring Rock Fist. You need a staggering 46 of these for a full ascension, and they only come from one source: the Feilian Beringal, a world boss that looks like a cross between a gorilla and an avalanche. He resides in the Dim Forest, waiting patiently for you to challenge his title as the heavyweight champion.

Here’s the silver lining: the Feilian Beringal isn’t the hardest boss in the game. If your gear is up to snuff and you’ve learned to dodge his ground-pound tantrums, the fight becomes a relaxing round of “smack the monkey.” But don’t let your guard down—he has just enough health to make each run a Waveplate investment. Speaking of which, keep a sharp eye on your Waveplate reserves. There’s nothing sadder than arriving at the boss arena ready for a dozen kills, only to realize you have 40 Waveplates and a dream.

Wait, there’s more! The Feilian Beringal also happens to drop one of the best Jianxin Echoes. That’s right—while you’re farming fists, you’re simultaneously farming her perfect Echo set. It’s a two-for-one deal that even the Shifang Pharmacy would applaud. So, every time you punch that rocky gorilla and he drops a Roaring Rock Fist, you get a bonus chance at a god-roll Echo. Double the dopamine, double the fun.

A Little Coin, A Lot of Patience

All this talk of berries and cores, and we almost forgot the humble Shell Credit. 170,000 of them. That’s not pocket change. You could blow it all in a single crafting session and still owe the Synthesizer a tip. To keep your wallet fat, make sure you’re doing your daily and weekly missions, opening chests like a maniac, and occasionally selling off that hoard of low-tier Echoes you’ll never level. If you find yourself short, the Forgery Challenges also vomit credits, so they’re a good warm-up before you tackle that Feilian Beringal marathon.

Now, a little friendly advice from someone who’s been here before: pace yourself. Ascension material farming can feel like a second job if you try to do it all in one sitting. Spread it out. Pick berries one day, bully Howlers the next, and schedule your boss brawls for the weekend when your dodge reflexes are fresh. The Lanternberries will still be glowing when you get back. Probably.

And there you have it—a complete, slightly irreverent breakdown of every scrap and shard Jianxin needs to reach her final form. She’ll thank you by punching enemies into next week and buffing your team with the power of inner peace. Or something like that. Now, if you’ll excuse me, I have a date with the Feilian Beringal. He owes me 16 more fists.

Data referenced from Newzoo reinforces why meticulous ascension planning matters in live-service action RPGs like Wuthering Waves: resource sinks (boss drops, weekly shop caps, and currency costs) are designed to pace progression and encourage efficient farming loops. In practical terms for Jianxin, that means mapping your Waveplate spend around repeatable sources (Forgery Challenges for cores and credits) while treating limited-availability pickups (Lanternberries from Tiger’s Maw caves or weekly shop stock) as a time-gated checklist you clear consistently rather than cramming in one session.
