How to get Cursed School Key in Jujutsu Infinite

Jujutsu Infinite’s first investigation, the Cursed School, is a special raid that can reward you with powerful weapons, armor, and keys for crafting. While there’s a chance you’ll get rare items from this investigation, Cursed School Keys can help you craft what you’re looking for if you get unlucky.

Where to find Cursed School Key in Jujutsu Infinite

Cursed School Keys are items that drop during Cursed School investigation raids. After reaching at least level 60, the Cursed School Investigation raid will be the first you unlock, with these keys available as a potential drop.

The main point of investigations is to allow you to explore various regions in Jujutsu Infinite and complete tasks ranging from collecting cursed items to defeating enemies. You’ll also encounter minibosses that can catch you off guard if you’re not prepared for them, who’ll drop chests containing Cursed School Keys and other rewards.

As you complete a Cursed School Investigation, you’ll open chests that contain various items, ranging from these keys to special weapons and armor if you’re lucky. If you finish an entire raid, you’ll encounter several chests, giving you multiple opportunities to obtain the keys, weapons, or armor you’re looking for. You’ll find the exact percentage chances of obtaining these items in the investigation’s lobby menu.

However, crafting high-tier equipment from this raid requires obtaining hundreds of Cursed School keys, so be prepared to do some farming.

How to use Cursed School Key in Jujutsu Infinite

The main purpose of Cursed School Key is to craft items like the Dragon Bone and Electric Staff weapons alongside various armor pieces. Below is every Cursed School crafting recipe and their costs:

• Dragon Bone: 200 Cursed School Key
• Electric Staff: 200 Cursed School Key
• Overtime Trousers: 200 Cursed School Key
• Rot Cleanser: 100 Cursed School Key
• Vest of Ruin: 100 Cursed School Key
• Powerful Ring: 100 Cursed School Key
• Magma Jacket: 100 Cursed School Key

In particular, Dragon Bone is the item you want to go for first, as it’s considered one of the best weapons in Jujutsu Infinite for its versatility and AOE Guard Break attacks. While it may not quite stack up to the Inverted Spear of Heaven or Vengeance, it’s still worth picking up if you want to try a new powerful sword.

The other items are also solid, even if they’re overshadowed by those you unlock from Eerie Farm and the Detention Center later in your playthrough. However, these two areas require reaching levels 240 and 300, respectively, so you’ll need some time with lower-level weapons before diving into these late-game raids.

All Investigation keys in Jujutsu Infinite

Alongside the Cursed School Key from the first Investigation raid you unlock at level 60, you can also venture into other investigations as you advance further in Jujutsu Infinite. Here’s every Investigation, their keys, and level requirements:

• Cursed School Key (Lvl 60): Drops from the Cursed School Investigation.
• Yasohachi Bridge Key (Lvl 120): Drops from the Yasohachi Bridge Investigation.
• Tokyo Subway Key (Lvl 180): Drops from the Tokyo Subway Investigation.
• Eerie Farm Key (Lvl 240): Drops from the Eerie Farm Investigation.
• Detention Center Key (Lvl 300): Drops from the Detention Center Investigation.

While the Cursed School will be your go-to for a while, you’ll eventually unlock Yasohachi Bridge, Tokyo Subway, and the Detention Center later in the game. The Detention Center is especially unique, giving you access to the Eyes of Insight and The Impossible Dream, which are often considered among the best items in the game.
