Undead Fire Weakness
by Jerrycyx
Undead Fire Weakness, a Forge mod for 1.20 – 1.20.4, makes undead mobs take more damage from fire.
What it does
Undead mobs take extra damage from flames in this mod, so fire becomes a more effective answer to zombies, skeletons and similar enemies. Players join without it, since only the server has to run the mod. The code is open source under the MIT License, and files exist for 1.20 – 1.20.4 on Forge.
Key features
Extra fire damage to undead
Flame damage dealt to undead mobs is increased, making fire a stronger tool against them.
Server-side operation
Only the server runs the change, so players on a server that uses it need nothing extra installed.
Built with KubeJS in mind
The author made the mod after finding no existing option covering this and KubeJS not fitting the task.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.

What the author says
I couldn't find any existing mods with the features I needed, and KubeJS wasn't quite up to the task either, so I spent a few hours making one myself.
