Insomniac Gaming Tensura Patches

Insomniac Server Patches

Insomniac Server Patches is a compatibility and bug-fix mod developed for the Insomniac Gaming Tensura modpack on Minecraft 1.21.1 (NeoForge).

It addresses conflicts between Tensura-related mods, fixes problems with character progression and resets, and removes overlapping systems that interfere with the modpack's intended gameplay.

This mod is primarily intended for the Insomniac Gaming modpack and is not recommended for general use without checking compatibility.

What does it change?

Tensura Horizons fixes

• Sovereign awakening restrictions: Disables automatic Sovereign Vessel acquisition and True Sovereign awakening through Tensura Horizons' status menu and /crosshorizon command. This prevents players from entering the affected progression path through those methods. Existing Sovereign data is preserved, and the separate Sovereign skill from Tensura Lower is unaffected.
• Void Spirit reset fix: Corrects an issue where fully resetting a character could leave their previous Void Spirit contract active, preventing them from obtaining another. After a full reset, players can once again receive a Void Spirit through prayer at a Praying Path and obtain its associated magic.

SlimeThrone Extras compatibility

SlimeThrone Extras provides useful additions, including new races, skills, and Lootr integration. However, some of its progression systems overlap with Tensura and ReRebirth, causing conflicts with character resets and skill management.

This patch preserves the useful additions while disabling conflicting systems:

• Skill locks and rebirth: Prevents SlimeThrone Extras from overriding Tensura's skill-lock storage and reset rules, allowing the modpack to use its intended ReRebirth mechanics.
• Simplified menus: Removes SlimeThrone Extras' redundant skill-lock button and prestige tab, avoiding competing interfaces and reset requirements.
• Disabled overlapping progression: Stops SlimeThrone Extras' separate quests, prestige progression, and related scheduling systems, leaving the modpack's chosen progression mechanics in control.
• Preserved content: Keeps SlimeThrone Extras' races, normal evolution paths, skills, functional skill menus, and Lootr/Charybdis integration available.

For players, these changes mean fewer conflicting progression systems, less confusing character management, and more consistent rebirth behavior.

Compatibility and installation

• Minecraft: 1.21.1
• Mod loader: NeoForge 21.1+
• Required: Tensura Horizons 0.31
• Optional: SlimeThrone Extras 2.1.2.1 (other versions are not supported)

Install the mod on both the server and clients. The client installation is necessary to remove obsolete SlimeThrone interface elements.

The original supported mods must remain installed; this patch does not replace or redistribute them.

Additional information

This is a targeted compatibility mod rather than a standalone content expansion. It does not add its own races, skills, or progression systems.

Patches are developed around the versions used by Insomniac Gaming and may not behave as intended with other mod combinations. Back up your world and player data before installing or updating.
