Published: November 2025
(Updated from May 2025)

Modding Tainted Grail: The Fall of Avalon has finally entered a new era. What was once a risky, trial-and-error process filled with unstable performance tweaks and manual file hacks is now a far more structured — and safer — experience thanks to officially supported tools.

If you’re exploring Avalon’s bleak, myth-soaked landscapes and wondering how to smooth rough edges, tweak balance, or enhance immersion without breaking your save files, this guide is your definitive reference. Below, you’ll find everything you need to know about modding Tainted Grail in late 2025, including what’s changed, what to avoid, and which mods are actually worth your time.

🚨 Critical Update Note (Read This First)

Mods for Tainted Grail: The Fall of Avalon

The single biggest change since May 2025 is the official release of modding tools on July 16, 2025.

This fundamentally reshaped how mods are created, installed, and maintained.

  • Older experimental methods — especially DXVK-based performance fixes — are now obsolete

  • Many pre-July 2025 mods cause crashes or invisible windows

  • Modern modding now relies on official frameworks and Unity-standard tooling

If you haven’t modded the game since launch or early access, do not reuse old guides.

🔧 The New Modding Landscape: Official Tools Are Here

Questline’s official support changed everything — but it didn’t instantly turn Avalon into a Skyrim-scale modding playground.

What’s New in 2025 Modding

BepInEx Is Now Essential
BepInEx has become the primary framework for loading mods. It’s a stable, widely trusted utility used across Unity games and is now the backbone of most Tainted Grail mods.

Steam Workshop? Not Yet
Despite official tools, there is no Steam Workshop integration.
👉 Nexus Mods remains the central hub for discovering, downloading, and discussing mods.

A Smaller-Than-Expected Scene
Even with official support, the modding scene remains relatively modest. This is due to:

  • The game’s niche audience

  • Unity modding being more complex than Creation-Engine-style games

  • A focus on QoL over massive content overhauls

💻 How to Install Mods in Late 2025 (Safe Method)

Manual installation using BepInEx is now the standard and recommended approach.

Step-by-Step Installation

  1. Update the Game
    Make sure Tainted Grail: The Fall of Avalon is fully updated (post-Update 1.1).

  2. Install BepInEx

    • Download the latest BepInEx release for Unity

    • Extract all files directly into your main game directory
      (usually: Steam\steamapps\common\Tainted Grail The Fall of Avalon)

  3. Install Mods

    • Most mods include a BepInEx\plugins folder

    • Place the mod’s .dll file into your own BepInEx\plugins directory

  4. Launch and Verify

    • Run the game once

    • Check BepInEx\LogOutput.log to confirm mods loaded correctly

⚠️ Save File Safety (Do Not Skip)

Always back up your saves before installing or removing mods.

Save file location:
%USERPROFILE%\AppData\LocalLow\Questline\Fall of Avalon

Mod conflicts rarely corrupt saves — but when they do, recovery is almost impossible.

🛠️ Current Mod Recommendations (Late 2025)

With official tools and recent patches in place, these are the mod categories that provide the best stability-to-benefit ratio.

🧹 Essential Quality-of-Life (QoL) Mods

Small tweaks that reduce frustration without altering the game’s core identity.

  • Weight Control / Inventory Tweaks
    Lightens the harsh encumbrance system and makes looting far less tedious.

  • Remove Item Requirements
    Allows the use of certain items (keys, quest objects) without arbitrary stat checks — helping prevent soft locks.

  • UI Scaling & Fixes
    Especially useful for ultrawide monitors or players who want cleaner menus beyond the official 1.1 improvements.

⚔️ Gameplay & Balance Tweaks

Ideal if you want to customize difficulty without turning Avalon into a power fantasy.

  • Combat Adjustments
    Mods that tweak parry windows, stamina regen, or enemy aggression for smoother combat flow.

  • Crafting & Economy Tweaks
    Expanded recipes or adjusted merchant prices that stay within lore-friendly balance.

  • Experience & Progression Mods
    Control how quickly attributes or skills level up to better suit long playthroughs.

🎨 Graphical & Audio Enhancements

These mods focus on immersion rather than raw performance.

  • ReShade Presets
    Improve color grading, contrast, and sharpness. Installed separately from BepInEx.

  • Audio Mix Adjustments
    Better balancing for combat sounds, ambience, and dialogue clarity.

❌ Performance Mods: A Strong Warning

The previously popular DXVK-GPLAsync workaround is now strongly discouraged.

User reports from October–November 2025 confirm it:

  • Causes frequent crashes

  • Creates invisible or non-responsive game windows

  • Conflicts with official patches and BepInEx mods

With performance improvements introduced in patch 1.15 (December 2025), these risky fixes are no longer worth using.

🆕 Game Updates & Expansion: Why They Matter for Mods

Tainted Grail continues to evolve — and official content updates directly affect mod compatibility.

Update 1.1 (September 2025)

A massive free update that added:

  • New Game+

  • Transmog system

  • New dungeons, quests, items, and enemies

This gave modders more systems and assets to build upon.

The Sanctuary of Sarras (December 15, 2025)

A paid expansion introducing:

  • A massive new zone

  • New bosses, enemies, and loot

  • A standalone narrative arc

This DLC represents the next frontier for content-focused mods.

🔮 The Future of Tainted Grail Modding

While stability has improved, growth remains gradual.

What to Expect Going Forward

  • DLC-Focused Tweaks
    Balance and QoL mods for Sanctuary of Sarras content.

  • Slow-Burn Overhauls
    Potential for new companions or quests — but only if the modder base grows.

  • Continued QoL Dominance
    Inventory, UI, and minor system tweaks will remain the most reliable mods.

📌 Final Modding Recommendations for 2025

  • Start with BepInEx — it’s the foundation for modern modding

  • Prioritize QoL mods for the best stability

  • Check mod dates and comments on Nexus Mods

  • Avoid anything released before July 2025 unless confirmed updated

  • Join the community via Nexus forums or Discord for compatibility updates

Modding Tainted Grail: The Fall of Avalon is now safer and more predictable than ever. While the library isn’t massive, the right mods can significantly enhance your journey through Avalon’s dying lands — just focus on smart, incremental improvements.
