About this Modpack

Diamon's SelfPack

A Colossal 470+ Mod Kitchen-Sink for 1.20.1 | A Sandbox with Character

Pack Banner

This is not a pack for weak PCs or a quick playthrough. It's a meticulously assembled, living world for Forge 1.20.1, where every mod is part of a greater ecosystem. Deep RPG, engineering creativity, and survival in a dangerous world are all woven together. We've spent hundreds of hours making the incompatible work together (just look at Simply Skills), so you get a ready-made epic sandbox.


🎭 The Two Sides of the Pack

🌟 Strengths (What It's Praised For) ⚠️ Considerations (What Requires Understanding)
Unbounded Depth: Full-fledged RPG skills (Simply Skills), magic (Iron's Spells), technology (Create + 40 addons), and exploration in one pack. Demanding on Resources: This is 470+ mods. It will not launch with less than 8 GB of allocated RAM. For comfort with shaders, 12 GB and a GPU like a GTX 1660 / RX 6600 are recommended.
A World Worth Exploring: Landscapes by Terralith & BWG, eerie Alex's Caves, hellish Incendium, and dozens of unique dungeons (YUNG's, Cataclysm). Not Perfectly Optimized: Despite Embeddium and ModernFix, FPS will dip in the densest forests or caves. This is the trade-off for scale.
Stability Within Chaos: The pack is tested. Version 7.0.1 is the result of fixing bugs and lag from past releases (avoid 5.0.0). Complex for Beginners: There's no built-in quest mod. You set your own goals: become a mage, an engineer, or a dragon hunter.
Full Integration: Even complex dependency chains (like those for Simply Skills) work out of the box.

⚙️ Performance & Real Talk

The pack can be laggy.

  • We are honest about this. With 470 mods, perfect optimization is a myth.
  • The main culprits (based on in-depth spark profiling) are usually aggressive mob spawns (like Artifacts mimics) and Java's Garbage Collector under load.
  • What we've done: Pre-configured performance mods and carefully balanced spawns where possible.
  • What you can do: Allocate 10-12 GB of RAM, use the Modrinth App for installation, and join our Discord for community-tuned configs and launch arguments that help mitigate lag spikes.

🚀 Getting Started

  1. Use the Modrinth App. It's the simplest way to install and manage the pack and its dependencies.
  2. Allocate RAM correctly: Set 10-12 GB (e.g., -Xmx10G) in your launcher before first launch.
  3. Join our community: For support, shared configurations, and showcases: https://discord.gg/7ZACpYe4.
  4. Choose your own path. The sandbox is yours.

Description crafted with AI assistance. The pack is a grand, ambitious project that can be laggy in dense areas but offers an unmatched scale of content for those with the hardware to support it.

Most common causes: insufficient RAM or wrong forge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 10 GB.

Can I add custom mods to Diamon's Selfpack without conflicts?

Yes, but check compatibility: only use mods for the same loader (forge) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

1) Increase RAM to 10 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time.
