OP Chests is a lightweight Paper plugin that adds fully custom, overpowered loot chests to your server.
Players can craft special chests that explode with randomized OP loot when placed — perfect for manhunts, SMP events, or chaotic progression servers.
This plugin is designed for Paper 1.21.10+ and uses custom recipes + persistent data tags to ensure every OP Chest behaves consistently.

🎁 Features
- Craftable OP Chests with custom recipes
- Tier‑based loot generation
- Nearly every slot filled with powerful items
- Randomized stack sizes (not always 64)
- Chests break and drop their loot (not the chest itself)
- Supports shift‑click bulk crafting
- Prevents renaming to avoid spoofing
- Works in single or double‑chest form
- Perfect for manhunts, SMPs, and chaos servers

⚠️ Important: Paper Double‑Chest Bug
Due to a known Paper issue, single chests do not always fire inventory events correctly when filled instantly.
Workaround:
👉 Place two OP Chests next to each other to form a double chest.
Double chests always generate loot correctly and drop the full contents when broken.
This is a Paper bug, not a plugin bug — and the workaround is 100% reliable.
**
When an OP Chest is placed:
- It waits briefly
- Fills all 27 or 54 slots with randomized OP loot
- Loot includes weapons, armor, tools, blocks, food, and rare items
- Stack sizes vary for chaos and balance
- Breaking the chest drops only the loot, not the chest
Double chests produce 54 items, fully packed.
