Mao’s Pendant sits in the left room of the castle during the Age of Safekeeping — reach it by grabbing the legendary sword instead of confronting the final boss, then pushing through the later main-story quests, since the pendant gates the game’s true ending.
Mao’s Pendant in The Adventures of Elliot: The Millennium Tales is one of those items you can lock yourself out of without realizing it, because the game hands you a tempting choice right before you’d ever know the pendant exists. The route runs straight through the main story, but it hinges on a single decision at the final-boss prompt — and getting that order wrong is what trips most players up. Here’s the exact path to reach it.
How to find Mao’s Pendant in The Adventures of Elliot
Reach the final-boss prompt

Progress through the main story until the game asks you to confront the final boss.
Take the legendary sword instead

Continue the next-era main quests

Push on through the Age of Budding, Magic, and Reconstruction main-story quests rather than ending the story early.
Arrive at the Age of Safekeeping
Keep following the main story until it carries you into the Age of Safekeeping, where the game directs you toward the pendant.
Enter the left room of the castle

Head into the left room inside the castle and the pendant is waiting there.
When the game prompts you to confront the final boss, don’t — grab the legendary sword first, because that single choice is what keeps the true-ending route open.

What Mao’s Pendant unlocks and the order that matters

Mao’s Pendant exists for one reason: it’s required to reach the game’s true ending. That’s also why the route is easy to miss. The story dangles the final boss in front of you well before it ever mentions the pendant, so it’s natural to just take the fight and roll credits — and that’s exactly the wrong move if you want the real conclusion.
The load-bearing part is the order. Picking up the legendary sword instead of confronting the boss, then carrying the story through the Age of Budding, Magic, and Reconstruction and into the Age of Safekeeping, is what eventually steers the game into telling you to find the pendant. Do those beats out of sequence and the prompt to collect it may never come. Treat this as a spoiler-aware checklist: sword first, later eras next, pendant last.
Frequently Asked Questions
Is Mao’s Pendant required for the true ending?
Yes. The pendant is tied directly to the game’s true ending — without it you won’t reach that conclusion, which is why the whole route is worth following carefully.
What happens if I confront the final boss before getting the legendary sword?
The true-ending path depends on taking the legendary sword at that prompt instead of fighting, so confronting the boss first is the mistake to avoid. The exact outcome of fighting early isn’t confirmed, but the safe read is that it skips the setup the pendant route needs — so grab the sword first and continue the main story.
Where exactly in the castle is the pendant?
Once the story sends you after it during the Age of Safekeeping, go into the left room of the castle. The pendant is sitting in that room.
