vault opener

Overview

Vault Opener is a lightweight client-side Fabric mod that watches ominous vault displays and automatically opens them when valuable loot shows up. Toggle it with a simple keybind so you never miss a Heavy Core or Wind Burst III book appearing.

Features

• One-touch activation with the H keybind to arm or disarm the auto-open behavior.
• Monitors the ominous vault display and triggers an immediate open when a Heavy Core or Wind Burst III enchanted book shows up.
• Fast reaction: opens the vault within a second of the item appearing.

How to Use

1. Load into your world and approach an ominous vault.
2. Press H to activate the mod (press again to deactivate). A short on-screen prompt confirms the state.
3. Open or view the ominous vault display as usual.
4. If a Heavy Core or Wind Burst III enchanted book appears inside, the vault will be opened automatically within a second.
5. When you’re done, press H again to disable the mod.

Known Limitations

• Only detects Heavy Core and Wind Burst III books; other valuable items won’t trigger opening.
• Relies on the item appearing for at least a moment; severe lag or high ping could cause missed detections.
• Requires the vault display to be visible; it won’t trigger if the vault UI isn’t open or in view.
