Latest Changes

Sukuna Appears Only When Challenged

Sukuna no longer spawns independently in the open world.

To summon him, speak to Itadori Yuji and select Challenge Sukuna.

Idle, non-combat Sukuna instances standing on the ground in older saves are automatically removed. Sukuna inside the city arena is not affected.

Two Malevolent Shrine Activations

After Gojo falls and the player begins fighting Sukuna directly, Sukuna activates Domain Expansion: Malevolent Shrine at:

• 60% remaining health
• 30% remaining health

Each threshold triggers one activation, for a total of two domain activations during this phase.

Post-Victory Return Dialogue

After defeating Sukuna, press E to speak to Itadori.

He reminds you to collect your rewards and equipment before leaving, and tells you that he will wait for five minutes.

Choose between:

• Return to Spawn: Teleport back to the world spawn point.
• Stay a Little Longer — Collect Loot First: Close the dialogue and remain in the arena.

Coming in Version 1.1.0 — Three-Language Support

Translation work is in progress. This feature is planned for version 1.1.0.

The mod will select its display language based on your Valheim language setting:

| Game Language | Mod Display Language | | --- | --- | | Traditional Chinese | Traditional Chinese, preserving the current wording. | | Simplified Chinese | Simplified Chinese, including support for Chinese-speaking players in Malaysia and Singapore. | | All other languages | English, with romanized Japanese technique names. |

The planned English localization will use these technique names:

| Technique | Planned Name | | --- | --- | | Blue | Ao | | Red | Aka | | Hollow Purple | Murasaki | | Unlimited Void | Ryoiki Tenkai: Muryokusho | | Malevolent Shrine | Fukuma Mizushi | | Black Flash | Kokusen | | Dismantle | Kai | | Cleave | Hachi | | Flame Technique | Fuga |

> Back up your world before experimenting with Hollow Purple. Outside boss fights, it can permanently alter terrain. Set DestroyTerrain = false under [Purple] in the configuration to disable this.

Getting Started

1. Find Gojo Satoru and Itadori Yuji near the starting stone circle.
2. Talk to Gojo with E and choose Cursed Energy Awakening.
3. Read his five-page Beginner's Guide.
4. Prepare your equipment and challenge Gojo.
5. Defeat him to obtain his gear and unlock the Sukuna challenge.

Gojo is intended as a mid-to-late-game challenge. Defeating vanilla Valheim bosses first weakens him through the Toji's Scars mechanic.

Cursed Energy and Black Flash

When you run out of CE, your melee attacks return to normal.

Black Flash

Every Cursed Strike has a chance to trigger Black Flash.

• Base activation chance: 3%
• Each equipped Gojo armor piece: +1%
• Each chain stack: +7%, up to four stacks
• Chain window: 8 seconds
• Damage multiplier: 2.5×, stacking with the Cursed Strike bonus

Black Flash features black-and-red lightning, a brief hit-stop, a red flash, an on-screen banner and combat music.
