Cursed Tools (Jujutsu Kaisen Supplement)

Cursed Tools

Cursed Tools are weapons and support items used by Jujutsu Sorcerers or Heavenly Restricted users that are purposefully imbued with a curse. They can be found spread around the world, but most are owned by Jujutsu High or are being heavily guarded at the Zenin's or Kamo's clan warehouse of cursed tools. Cursed tools count as magic items and objects.

If you're a Heavenly Restriction you may use your Constitution modifier instead of Charisma for all cursed tools.

Cursed Damage

Almost all cursed tools have cursed energy imbued into them, making them stronger. They add one additional set of dice to the normal weapon's damage dice, that deals necrotic damage, and adds the user’s Charisma modifier to that damage. For every grade above four, this additional damage dice increases by one tier. Example: Grade 4 Katana is 1d8 slashing damage + 1d8 + Charisma modifier necrotic damage. Grade 3 Katana is 1d8 slashing damage + 1d10 + Charisma modifier necrotic damage. Grade 2 Katana is 1d8 slashing damage + 1d12 + Charisma modifier necrotic damage. Grade 1 Katana is 1d8 slashing + 2d6 + Charisma modifier necrotic damage. Special Grade Katana is 1d8 slashing damage + 2d8 + Charisma modifier necrotic damage. Additionally the tool adds a bonus to their attack and damage roles equal to 4 minus their grade, with Special Grade being treated as 0.

Cursed Tool Durability

In the world of jujutsu, weapons and cursed tools have Durability that reflects their resilience against forces and physical impacts. The Durability of an item decreases with usage, especially in high-energy battles, and can be damaged or destroyed in intense encounters.

Grade	Durability	Damage Threshold
Grade 4	50	50
Grade 3	100	100
Grade 2	150	150
Grade 1	200	200
Special Grade	500	400

Conditions for Reducing Durability: Below are the situations that weaken Cursed Tools over time, gradually wearing down their strength and durability.

• Area Effects: If the creature holding the Cursed Tool is subject to an Area of Effect Saving Throw, the Cursed Tool takes the same damage as the wielder would, unless stated otherwise.

• Attacks Directly Targeting the Item: If a creature specifically targets a cursed tool, they must succeed on an attack roll against its AC (determined by grade + Wielder's Dexterity or Strength, user's choice).

Grade	Base Armor Class
Grade 4	10
Grade 3	13
Grade 2	15
Grade 1	20
Special Grade	30

• Extreme Temperature/Corrosive Elements: Items exposed to these environments take 1d6 damage every minute.

Durability Loss Effects As Durability decreases, items lose effectiveness. Each threshold below offers unique drawbacks:

Durability	Effect
50%	-1 To Hit and the damage die tier is reduced by 1, if the die tier cannot be reduced it receives a -10 damage penalty.
25%	-2 To Hit and the damage die tier is reduced by 2, if the die tier cannot be reduced it receives a -20 damage penalty.
0%	Weapon Shatters and becomes Unusable.

Repairing Durability

Basic Repairs: With the Cursed Blacksmith feat, a sorcerer can restore full Durability during an 8 hour period, requiring cursed energy or high-quality materials worth at least a tenth of the item’s value.

Enhancing Cursed Tools

By constantly infusing their weapons with Cursed Energy, Cursed Tools can gradually become stronger. The table below details the number of times Cursed Weapon Enhancement must be used on the weapon in order for it to be upgraded to the next grade. Only the first Cursed Weapon Enhancement performed outside of combat each day counts towards creating a tool like this, unlike in combat where all are counted as normal.

Grade	Cursed Weapon Enhancement Uses
Semi-Cursed	25
Grade 4	50
Grade 3	75
Grade 2	100
Grade 1	125
Special Grade	150

This chain can be attached to other weapons and extend the reach of said weapon as far as your Strength can allow. For every point your Strength modifier has the chain can extend a weapon's range by 20 feet. So for example if your strength modifier is a +4, the weapon's range can be extended by up to 80 feet.

However, this has a downside. Whenever a non-attack related feature of the weapon would be used during time until the start of your next turn after using the chain, you have to compare your Strength modifier with the attack bonus or save DC - 8 of the attack or feature which would necessitate such a feature, if any. If your Strength modifier is lower, you can’t pull the weapon back in time to use the feature.

As a reaction to being hit by an attack imbued with cursed energy you're able to use the rope in order to have the rope take the damage in your place. The rope has resistance to all damage imbued with cursed energy. Additionally as an action you can attempt to restrain an enemy with the rope who can either make a Dexterity saving throw to avoid it, or a Strength save to break out of it, against a DC equal to (8 + your Dexterity or Strength modifier + proficiency bonus). Upon being caught by the rope the target will be considered restrained and unable to use cursed techniques. They can attempt to break free from the rope at the start of each of their turns by making a Strength against the DC, escaping on a success and remaining trapped on upon failure. You may also have this effect when grappling a creature while wielding the Black Rope. Attacks from the rope will ignore defensive cursed techniques, and whenever they do the rope takes damage equal to the cursed energy spent on the defensive technique.

Finally on a short or long rest you can imbue cursed energy into the rope to restore its lost hit points. On a short rest you can imbue as much Cursed Energy as your Charisma modifier, and on a long rest you can imbue as much as you'd like. The rope heals 15 hp per Cursed Energy spent.

Hiten

Sukuna holding the Hiten, [27]

Weapon (Trident), Legendary

When attacking with Hiten you gain a +4 to your attack and damage rolls, and deal an additional 2d6 + your Charisma modifier necrotic damage.

The action cost is a bonus action to summon and a free action to mount.

Supreme Martial Solution. If someone were to have both Supreme Martial Solution and Hiten can create a special reaction between the two cursed tools. If the lightning specifically targets Hiten’s cloud, due to the compatible cursed energy the cloud absorbs the electricity then erupts in a massive electrical explosion. Every person within 60 feet must make a Dexterity saving throw and taking 30d12 lightning damage in a failure. Half as much on a success. This can only be done once per long rest as the cursed energy will not synergize for a period of time.

Fanmade Cursed Tools
