GuakRogueWaves

Multiplayer-synced rogue ocean waves for Valheim.

When a player is controlling a moving ship, the mod occasionally sends a rogue wave through the water near that ship. Everyone with the mod installed receives the same wave event, so the water timing, position, direction, and height match across clients.

Defaults

• Wave height: 9 meters, roughly 30 feet
• First wave: about 35 to 75 seconds after sailing starts
• Later waves: about 90 to 210 seconds apart
• Warning text: ROGUE WAVE
• Multiplayer sync: enabled

Install

Import this zip into r2modman, or extract the package into your Valheim profile's BepInEx plugins folder.

All friends on the server should install the same version. Players without the mod will not see the synced wave height.

Config

After first launch, edit:

BepInEx/config/eden.valheim.roguewaves.cfg

Useful settings:

• HeightMeters
• MinSecondsBetweenWaves
• MaxSecondsBetweenWaves
• SyncWaves
• ChatWarning

Changelog
