Hazards!
by McJty
Hazards! adds configurable bad effects to the world, so rain, sunlight and polluted areas can deal damage or apply potion effects to players, villagers and animals.
What it does
Modpack makers mostly use it to add challenge to a world. Rain can be made deadly, sunlight can burn, and selected areas can be marked as polluted. Each hazard is tuned separately, and damage can be straight damage, potion effects, or both. Passive animals and villagers can also be set to suffer from the same effects.
Radiation is controlled per dimension, so one world can have a dangerous Nether while the Overworld stays calm. A radiation monitor shows how strong the exposure is at the player's position. Armor can be configured to protect against specific hazards, which lets a pack pair the challenge with its own gear progression.
The mod is open source under the MIT License and runs on Forge for 1.16.5 and 1.18.2 only. Installation covers the server and each player's game. The latest Forge file is 1.18-1.0.0 for 1.18.2, a beta release from 2023-01-26, and no later build has been published.
Key features
Deadly rain
Rain can be set to damage players or apply potion effects while they stand in it outdoors.
Radiation per dimension
The radiation level is set for each dimension, so hazards can differ between the Overworld, Nether and End.
Radiation monitor
A monitor shows the current radiation exposure, so a player can tell how much danger they are in.
Hazards for mobs
Villagers and passive animals can be made to suffer from the same bad effects as players.
Configurable armor
Armor can be set to resist particular hazards, letting pack makers tie protection to specific items.

Use cases
Who it’s for: Modpack makers who want to add challenge to a world without writing code, and server owners running a shared survival pack who need the same hazard rules for every player.
How it compares
Origins: Accessibilities is open source under the MIT License, runs on Forge for 1.16.5 – 1.19.2 and is client and server, so it covers a different set of accessibility changes rather than world hazards. Solar Hardcore is for 1.16.5 only, is client and server, and is published under All rights reserved, so it is not open source. Old not bad is open source under the MIT License, targets 1.20.1 only, and is server-side only, so players join without installing it.
