Diamon's SelfPack
A Colossal 470+ Mod Kitchen-Sink for 1.20.1 | A Sandbox with Character
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
sparkprofiling) 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
