Domain Expansion Mod

Adds multiplayer-ready Domain Expansions inspired by Jujutsu Kaisen to Lethal Company.

Domains

• Infinite Void
• Malevolent Shrine (closed barrier)
• Malevolent Shrine (open barrier)
• Idle Death Gamble with rolls, jackpots and regeneration
• Self-Embodiment of Perfection with distance-based soul drain and synchronized soul meters

Press F1 to open the Domain menu, choose with 1-5, and press Enter to activate. Direct Domain shortcuts have been removed. Each player receives the configured number of domain uses after the ship lands and returns to zero uses in orbit.

Hollow Purple

Press F2 to open the Ability menu, select Hollow Purple with 1, and press Enter while alive on a landed moon. The synchronized 20-second sequence follows distinct anime-inspired stages: Lapse Blue forms first, Reversal Red ignites separately, both spiral together, and their collision creates a compact violet imaginary mass with a release shockwave. Walking remains locked during charging, camera aiming remains available, and the caster receives charge i-frames. At release, Hollow Purple snapshots the caster's current view direction and can no longer be steered.

The large layered plasma projectile travels forward for 20 seconds with expanding shock rings, dragged debris, a luminous corona and a broad destructive wake. It passes through level geometry, instantly defeats contacted players and enemies except its caster, and uses host-authoritative multiplayer hit detection. Its supplied theme plays from 02:05 to 02:53; release occurs at 02:25, approximately one second before the 02:26 drop.

Configuration

Open LethalConfig and select LethalCompanyMod to edit:

• Domains Per Moon - sets how many domains each player can use per landed moon (1-20).
• Infinite Domains (Debug) - gives every player unlimited domain uses while landed.

In multiplayer, the host's values control the lobby and are synchronized to every client.

Multiple separate domains can exist at the same time. You may open a domain whenever you are not currently inside another domain. Closed domains use isolated session arenas and leave an opaque, solid black barrier sphere at their casting location until that specific domain closes.

For synchronized multiplayer behavior, every player should install the same version. The separate Ability menu and revised Hollow Purple sequence require all clients to use version 1.20.0 or newer.

Update Coming Soon

The next Domain Expansions currently in development are:

• Time Cell Moon Palace - Naoya Zenin's Domain Expansion
• Chimera Shadow Garden - Megumi Fushiguro's Domain Expansion

Hotfixes are planned for release twice per week to keep the mod stable while new content is being developed.

Installation

Install with a Thunderstore-compatible mod manager, or copy the compiled DLL into BepInEx/plugins/LethalCompanyMod.

Thunderstore installs these required packages automatically:

• BepInEx-BepInExPack-5.4.2305
• AinaVT-LethalConfig-1.4.6

When importing the ZIP as a local mod, install both requirements manually because local imports do not resolve Thunderstore dependencies.
