Starting the Quest
Unlock Condition: Reach Level 30.
- Open your Quest Menu and go to the Personal tab.
- You will see a quest named "The Power of Kings".
- Once you hit Level 30, the progress bar will fill, and you can claim it.
⚠️ First Step: Find the "Distressed Individual" NPC in the lobby. He has a marker above his head. Talk to him to begin.
Step 1: The Chess Puzzle
Location: Ninja Forest (Story Mode).
Enter Ninja Forest story mode. Look for Chess Boards scattered around the map. Interact with the one that lets you play.
You need to checkmate the King (Spiky Hair guy) in 4 moves.
Move 1 King to 73
Move 2 Rook to 81
Move 3 Pawn takes Queen
Move 4 Queen to 88
After completing, return to the lobby and talk to the "Mysterious Woman" (Witch) to get the next quest.
Step 2, 3 & 4: The Grind
Complete these tasks in order.
Wave 80 Run
Infinite
Go to Infinite Mode (Easiest Map). Reach Wave 80.
⚠️ Warning: You MUST lose on purpose after Wave 80. Do not leave the game, or it won't count.
Kill 15 Bosses
Fastest Method
Go to Infinite Ninja Forest. Bosses spawn at Wave 10 and 20.
- Kill Wave 10 Boss.
- Restart game instantly.
- Repeat 15 times.
Upgrade 75 Relics
Gold Sink
Use your AFK farmed relics. Just upgrade random low-tier relics +1 level each. It's the cheapest way to hit the 75 count.
Final Step: Place 5000 Units
The "Cheese" Strategy.
The Fastcart Macro Method
Placing 5000 units normally takes forever. Use Fastcart because he costs 0 Yen to place.
- Go to Infinite Mode (Low Ping server).
- Place a strong unit (e.g. Kenpachi) at spawn to hold the wave.
- Use a macro or manually spam: Place Fastcart -> Sell (Press X) -> Repeat.
Speed: ~2 units/second. Total time: ~45 minutes.
Reward: Leouch
