While exploring the Abbasiyah District, you also have to get the House of Wisdom Gear Chest, which counts as one of the six Assassin’s Creed Mirage collectibles required to reach 100% completion in the western region of Baghdad. The AC Mirage House of Wisdom Gear Chest contains the Abbasid Knight Sword / Upgrade Schematic, but to get your hands on it, you’ll need to find the chest’s key.
Since the chest is on the roof of the House of Wisdom and because it is guarded by a lot of soldiers, it can be trickier to reach. Furthermore, the Gear Chest Key is also a bit hard to spot.
AC Mirage House of Wisdom Chest Location
The House of Wisdom Chest in Assassin’s Creed Mirage is on top of an impressive building in the northwestern corner of Abbasiyah. You can see the chest’s location marked on the following map so you can easily identify the landmark you’ll need to visit.
To make the guide easier to follow, I recommend approaching the House of Wisdom from the east. Enter the building’s courtyard because it’s not a hostile area, then look around for a wooden platform near the northwestern wall. You can see the platform or the structure in my screenshot below, and you’ll need to climb on it to get to the roof.
Inside the tower marked in my screenshot above is the House of Wisdom Gear Chest; however, as mentioned above, to open it, you’ll need a key.
Where To Find the Assassin’s Creed Mirage House of Wisdom Chest Key
The key for the House of Wisdom Gear Chest in Assassin’s Creed Mirage is carried by a scientist found on the roof of the large landmark. To find the scientist from the location of the chest, you’ll have to reach the northeastern side of the roof, as shown below.
Remember that the NPC with the key is on top of the roof, so you don’t need to deal with the guards below. Furthermore, the scientist is not protected by any of the guards, and as you can see below, he is busy studying, which makes him an easy target for pickpocketing.
After you get the Astronomical Library Key, head back to the tower (also visible in the screenshot above), but do not go inside just yet. Instead, use the lift by the entrance to get to the roof. Next, you’ll want to go around the balcony looking for a broken railing in front of a barred window.
While standing near the broken railing, as pictured above, use one of Basim’s throwing knives to hit the red link (locker) on the chandelier inside the tower. When the chandelier falls to the ground, it will hit some explosive jars, thus creating a hole in the breakable floor.
Finally, return to the tower’s base, open the House of Wisdom locked door with the Astronomical Library Key you obtained, and use the bookshelves to ascend to the top floor where the Gear Chest awaits.
