Craftable OP chests

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.

🧭 Perfect For

• Manhunts

• Custom challenges
• Speedrun modifiers
• PvP loot drops
