# Windrose World Modifiers (Custom Difficulty) (/docs/windrose/world-modifiers)



import { Step, Steps } from 'fumadocs-ui/components/steps';

Custom world modifiers let you fine-tune every aspect of Windrose's difficulty. Each modifier is set individually in `WorldDescription.json` under `WorldSettings`.

> **Tip:** Setting any custom value automatically changes `WorldPresetType` to `"Custom"` on next server start. If you want a clean preset instead, see [Difficulty Presets](/docs/windrose/difficulty-presets).
