Sync
<table><tr><td width="900">
MonsterDB includes full server synchronization support so all clients stay consistent with the server's configuration.
| Step | Description | |:---|:---| | Game Load | Plugin starts and reads all files from the Import folder | | Server | Loads imported files, creates clones, and applies all updates | | Client | Waits for files from the server, then creates clones and applies updates | | FileWatcher | If enabled, any changes made on the server are automatically sent to all connected clients |

RRR
<table><tr><td width="900">
To convert RRR.json files into MDB.yml files, install https://thunderstore.io/c/valheim/p/ValheimModding/JsonDotNET/ to gain access to command: monsterdb rrr which will look for files within folder RRR at BepInEx/config/MonsterDB/RRR
RRR Converter was designed to parse both RRR.json and DropThat.cfg to coalesce into MDB.yml
