🛡️ OPACA – Open Parties and Claims Additions
An extension mod that adds powerful new protection rules to Open Parties and Claims (OPAC).
📜 What is OPACA?
OPACA (Open Parties and Claims Additions) expands the popular Open Parties and Claims system by introducing advanced rule options for even finer control over land protection and player interactions.
One key feature: dimension-specific protection!
For example, you can configure claims to only apply in claimable dimensions—allowing the Overworld to be protected while leaving other dimensions free for activities like mining.
🧩 Perfect For:
- 📜 Custom Modpacks – Fine-tune survival, PvP, or roleplay servers
- ⚙️ Server Administrators – Gain more control without having to rewrite existing protection systems
🔥 Compatibility
- ✅ Fully compatible with Open Parties and Claims
- ✅ Lightweight and directly integrates into the Open Parties and Claims config
