In Pokémon Legends ZA, there’s far more waiting for dedicated trainers beyond the main story. Hidden deep within the postgame lies a secret side quest that only becomes available once you’ve proven yourself in the challenging Infinite Royale. Many players have missed it entirely, but with the right approach, this quest can become one of the most rewarding parts of your adventure—especially if you’re aiming to farm battles efficiently and earn your coveted Shiny Charm.

How to Unlock the Secret Side Quest

To access this quest, you’ll first need to dive into the Infinite Royale, which unlocks after completing the main game. This mode pits you against an endless string of trainers, but the key milestone is reaching 20 total wins.

It’s important to note that the game gives no hints about this quest beforehand—there’s no marker, no dialogue clue, and no visible prompt. Only after achieving your 20th victory will a new side quest icon appear on your map, marking the start of an exclusive encounter with a character named Lean Leane.

While the Infinite Royale itself offers valuable rewards such as Master Balls, Apricorn Balls, and Bottle Caps, the true prize comes once you cross that 20-win threshold.

The Encounter with Lean Leane

After completing your 20th win, you’ll unlock access to Lean Leane’s room, triggering a short cutscene that transitions into a tournament-style battle against her. The challenge consists of four consecutive battles, all featuring her fairy-heavy lineup.

Fortunately, her team remains identical every time you fight her—same Pokémon, same levels, same strategy. That means with the right setup, particularly an Excadrill with Iron Head, you can clear her battles in minutes.

Because Pokémon Legends ZA removes the usual PP limits in this mode, you can spam Iron Head or Drill Run without worry, making this an extremely efficient method for repeat battles.

Why This Quest Matters: Farming for the Shiny Charm

The most significant benefit of this side quest is its use in farming battles toward the 1,000-win requirement for the Shiny Charm. Since you can fight Lean Leane repeatedly with minimal setup, this is currently the fastest and most reliable method for accumulating wins.

Each run nets you 300,000 Pokédollars and 30 Luxury Balls, making it not only great for experience and progress but also for filling your item bag with style. If you’re someone who enjoys training, customizing, and showing off rare Pokémon, these rewards are a solid bonus.

Speaking of rare Pokémon, players who enjoy collecting special variants may also want to explore options to buy custom Pokémon or even buy custom shiny ZA Pokémon, as these can complement your in-game achievements and complete your dream team.

Expert Tips for Efficiency

• Stick with Excadrill: Its Steel typing and Iron Head make it ideal for countering fairy-based teams.

• Cycle battles quickly: Since the match setup is always the same, you can focus purely on speed and repetition.

• Keep track of wins: Even though the game doesn’t track your total in one place, make sure to note your progress toward the 1,000 mark.

• Use the rewards wisely: The extra money and Luxury Balls can help with other postgame challenges, including breeding, customization, and trading activities.

The secret side quest in Pokémon Legends ZA is one of those hidden gems that perfectly rewards persistence. It’s tucked away behind a high challenge wall, but once unlocked, it transforms into an incredibly efficient route for both farming wins and enjoying endgame battles. Whether you’re grinding for the Shiny Charm, collecting special Pokémon, or just exploring every secret the game has to offer, this quest is a must-complete for any dedicated trainer.
