Assassin’s Creed Shadows: All 13 Isu Glyph Locations and How to Open the Door

Summary

The Isu Glyph Door puzzle was added in update 1.1.6 and asks you to find 13 hidden symbols spread out across the Yamashiro, Omi, Wakasa, and Tamba regions

Players must start the “A Puzzlement” quest in Genbu Highlands and put on Riddle Scroll Beacon trinket to find nearby symbols by listening for chimes

Opening the door gives you legendary weapons like the Isu-Forged Spear and Tanto, Atlantis engravings, and the first part of the Blade of Yumminess

Update 1.1.6 added one of the most interesting puzzles to Assassin’s Creed Shadows with the mysterious Isu Glyph Door. This quest, called “A Puzzlement,” sends Naoe and Yasuke on a treasure hunt across several regions with very little help. Knowing where to start, how to use the detection tool, and where each symbol is makes this tricky scavenger hunt much easier.

Starting A Puzzlement Quest and Getting the Riddle Scroll Beacon

You can start the Isu Glyph Door quest right after you unlock Yasuke as a playable character once you have update 1.1.6. The quest begins in the Genbu Highlands. The fastest way to get there is to fast travel to Hanazono Castle.

Upon arriving at the marked location, players encounter two NPCs named Kinu and Kane who discuss a strange door covered in mysterious symbols. These characters believe treasure lies beyond the sealed entrance and provide Naoe and Yasuke with a crucial tool—the Riddle Scroll Beacon trinket. This item must be equipped from the inventory’s trinket section.

The Riddle Scroll Beacon makes a sound when you get close to hidden symbols, helping you know where to look. The first symbol shows up on your map as part of the quest, but the other twelve do not, so you have to search carefully in the four main regions: Yamashiro, Omi, Wakasa, and Tamba.

All 13 glyphs are etched into natural features such as boulders, cliff faces, and rocky walls throughout the map. Here’s the comprehensive location guide organized by region:

Efficient Glyph Hunting Strategy

Instead of searching the whole map at random, use these simple tips to make finding the symbols easier:

Try to finish one region at a time to cut down on fast travel and keep track of where you are. The suggested order is Yamashiro, then Omi, Wakasa, and Tamba, but you can choose your own path.
Listen for sound clues because this helps you know if you are close or not. The Riddle Scroll Beacon is very helpful. When the chime gets louder, you are near—look at cliffs, big rocks, and rocky walls nearby.
All glyphs appear on natural formations. Focus on checking big rocks, cliffs behind viewpoints, and rocky areas near water. Traveling to nearby viewpoints and shrines reduces travel time significantly.

Unlocking the Door and Claiming Rewards

After you find all 13 glyph, go back to the first quest spot in the Genbu Highlands where you met Kinu and Kane. A cutscene will start when you get close to the door, showing the way into the hidden room.

Inside the room, you will see a big Kassandra statue, who is a main character from Assassin’s Creed Odyssey. This is a fun secret for longtime fans. Next to the statue is a crafting machine marked “Parts Missing,” which you will use when you collect all the pieces for the legendary Blade of Yumminess katana.

Conclusion

The Isu Glyph Door puzzle is one of the best challenges in Assassin’s Creed Shadows update 1.1.6, giving you great legendary gear and the fun of exploring different parts of feudal Japan. Finding all 13 glyphs gives you excellent legendary weapons and engravings. The quest successfully blends challenging treasure hunting with great rewards. Make sure you complete the “A Puzzlement” quest right away.
