TerrainImpact

When giant monsters fight, they should scar the landscape. Terrain Impact fixes that. Keep it subtle, or turn it all the way up and let the geology become part of the joke.

Terrain Impact

When giant monsters fight, they should scar the landscape. Terrain Impact fixes that. Keep it subtle, or turn it all the way up and let the geology become part of the joke.

The defaults are intentionally mild. Raise the strength, radius, or frequency if you want giant battles to chew up the landscape.

> Tip: With devcommands enabled, use terrainimpact max for extreme > settings or terrainimpact min to restore the defaults. The commands save > the same values shown in the BepInEx configuration file.

Configuration

After the first modded launch, edit BepInEx/config/ChorusReef.TerrainImpact.cfg through r2modman's Config Editor or a text editor.

| Setting | Default | Range | Effect | | --- | ---: | ---: | --- | | Impact Strength | 1 | Whole numbers 1–99 | Controls how aggressively each accepted hit lowers terrain. | | Impact Radius (m) | 1.5 | 0.5–40 | Controls the affected width. Very high strength adds width beyond this base radius. | | Global Cooldown (s) | 10 | 0–120 | Minimum time between accepted terrain edits, shared by all qualifying attacks. | | Stone Drops | false | true/false | Allows or disables Stone drops from creature impacts. |

At the defaults, one accepted impact makes roughly one ordinary pickaxe dent. The dig target is -0.5 × Impact Strength metres. Above strength 16, each additional point also adds 0.5 m to the radius. Valheim limits each terrain vertex to about 8 m below its original height, so higher strength primarily expands the affected area.

Extreme settings are deliberately destructive. One qualifying hit can remove a large section of ground, expose deep terrain, or push land below sea level. Test aggressive settings in a disposable area or world first.

Notes

Terrain Impact uses Valheim's terrain modification system, so edits persist with the world. Qualifying attacks include selected ground impacts from Trolls (including Trollstaff summons), Lox, Fuling Berserkers, Seeker Soldiers, and Abominations. Other attacks and the Trollstaff meteor arrival are unaffected.

This mod is especially noticeable in worlds where large creatures fight frequently or appear outside their normal biomes. Local-host play has been tested; multiplayer behavior has not yet been validated.
