The Perception Blocking Mask is a wearable in Jujutsu Infinite which comes with great defensive stats. It’s one of the better tools for tanky builds and will come in handy especially if you are struggling against certain content and bosses.
The mask is a Legendary item, therefore obtaining it is not going to be easy. So if you are having a hard time getting your hands on it in the Roblox game, then the guide below will help you out.
How to get the Perception Blocking Mask in Jujutsu Infinite
There are three ways to obtain the Perception Blocking Mask in Jujutsu Infinite:
1) Obtained as a drop from Investigation Chests
The first method relies on a fair bit of luck but is much quicker. You can get the Perception Blocking Mask as a drop by opening Investigation Chests when completing Detention Center Investigations.
The RnG on it is pretty dreadful, but if you are lucky you might just be able to get the item right away.
2) Craft it with Detention Center Keys
Like most tools and accessories you will be able to craft the Perception Blocking Mask as well in Jujutsu Infinite. For that, you will need 100 Detention Center Keys which too are obtained by completing Detention Center Investigations.
However, this method is a bit more time-consuming as obtaining the required amount of keys requires a lot of grind.

3) Trade it with other players
The mask is a B-tier tradeable item and you will be able to trade for it with other players. If you have something that they want, you can always exchange it for this mask.
Jujutsu Infinite Perception Blocking Mask stats
As mentioned, the Perception Blocking Mask has one of the best defensive stats in the game. It comes with a Health boost of 71.5 points, making it ideal for those who are going for a more tanky build.
Moreover, the tool also comes with a passive called Perception Block. This ability will provide you with a 20% damage boost when you are taking down a horde of enemies.
It also provides you with a chance to initiate the battle whenever you want, giving you more room to experiment with the rest of your build.
