⚠️ Common Mistakes

Installing multiple mods that modify the same files without checking compatibility

👍 Pros

Tiny but dedicated following (16 endorsements) — the kind of mod that solves a specific problem for server admins.
Fresh update (July 2026) so it's likely compatible with current Valheim versions.
Server-side only means no client mods needed — players can join without installing anything.

👎 Cons

Very low endorsement count (16) — this is a niche tool, not a mainstream mod.
No documentation or examples provided in the description — you'll have to figure out the rule syntax yourself.
Requires server access to use — if you're not hosting your own server, this mod is useless to you.
