BossGate
BossGate is a lightweight Valheim mod that lets admins enable/disable boss summons per world.
By default, all bosses are blocked, so players can’t progress bosses without admin approval.
Changes apply instantly (no restart).
Features
- ✅ Server-authoritative boss gating (blocks boss summon attempts)
- ✅ Simple in-game admin UI (toggle bosses on/off)
- ✅ No server restart required (uses world global keys)
- ✅ Optional: block the Queen door until the Queen is enabled
- ✅ Chat / center-screen message when a summon is blocked
- ✅ Works in local host for testing (host is treated as admin)
How it works (simple)
BossGate blocks boss summons when a boss is disabled.
Boss availability is saved as world global keys, so it persists with the world.
Installation
You can install manually, but for most people it’s easier to use r2modman / Thunderstore.
Manual install (Client / Singleplayer / Local host)
- Install BepInEx 5 for Valheim.
- Unzip mod folder into:
Valheim/BepInEx/plugins/
- Launch the game once.
Manual install (Dedicated Server)
- Install BepInEx 5 on the server.
- Unzip mod folder into:
Valheim/BepInEx/plugins/
- Start/restart the server once to load the plugin.
- Add your SteamID64 to the server
adminlist.txt.
Only the server needs the mod to block summons.
Admins need the mod on their PC to use the in-game UI.
Usage
- Press F7 to open/close the BossGate admin window.
- Toggle bosses ENABLED / DISABLED.
- Use Enable all / Disable all for quick setup.
Default behavior
All bosses are disabled until an admin enables them.
Configuration
A config file is generated after first launch:
BepInEx/config/bossgate.cfg
Common options:
- UI toggle key (default:
F7) - Blocked message text (supports
{boss}) - Show message in chat and/or center screen
- Block unknown boss altars (safer)
- Block the Queen door while Queen is disabled
Notes
- Local host testing: the host is treated as admin automatically.
- Dedicated servers: admin permissions come from
adminlist.txt(server-side).
