Debuff Zones
by sylvxa
Debuff Zones lets a server owner mark areas that apply status effects to players who enter them, as a softer add-on to the vanilla world border.
What it does
Debuff Zones is a server-side Fabric mod that adds an alternative to the vanilla worldborder system. Instead of a hard wall, areas can apply debuffs, so players face a gradual penalty for going beyond a set region. It requires Fabric API, and only the server needs it, so players join without installing anything. Files are published for Fabric 1.21.11, with 1.1.0 as the latest build, released under the MIT License and open source.
Key features
Softer world border
Players who cross the boundary are slowed down by effects rather than stopped by an impassable wall.
Configurable zones
Zones are defined on the server, so the owner decides where the penalties apply and how strong they are.
Server-side operation
The mod runs on the server alone, so clients need nothing extra to enter the affected areas.
