Customizing Structure Spawning and Terrain Integration

Adjust Terrain Height Ranges

Structure JSON files contain allowed_terrain_height_range settings that control where arenas spawn relative to world elevation. Modify these values to:

• Restrict arenas to mountain peaks only
• Allow spawning in valleys and lowlands
• Prevent structures from generating in incompatible terrain

Higher range values permit spawning across wider elevation bands; narrower ranges create more selective placement.

Control Structure Frequency

Edit structure set files to change spacing and separation values:

• Spacing: Distance between structure attempts (larger = fewer arenas)
• Separation: Minimum distance structures must maintain from each other

Increase both values to make boss arenas rarer and more rewarding to find. Decrease them for more frequent encounters.

Ensure Biome Mod Compatibility

If using custom biome mods, verify that structure set files reference your installed biomes. Arenas should spawn naturally in custom terrain. Check configuration files to confirm biome tags match your world generation setup, ensuring structures blend properly with modded landscapes.
