**Extreme Clime**
Extreme Clime is a Minecraft mod that adds dangerous weather events to make survival more challenging and immersive.
The first feature introduced is Acid Rain, a toxic storm that transforms normal rain into a hazardous environmental event that damages players and mobs.
If you enjoy harder survival, environmental hazards, and dynamic weather, this mod adds a new layer of danger to storms.
Acid Rain
During certain storms, rain becomes acidic, creating a dangerous environment across the world.
When Acid Rain occurs:
Players take damage when exposed to the rain
Hostile and passive mobs are affected
The sky and atmosphere turn toxic green
Acid rain particles fall during the storm
Toxic ambient sounds enhance the atmosphere
Taking shelter under blocks or inside structures will protect you from the rain.
This event makes storms more threatening and adds tension to exploration and survival.
Commands
You can control the event using commands:
/extremeclime acid start <seconds>
Starts an Acid Rain storm.
/extremeclime acid stop
Stops the Acid Rain event.
/extremeclime acid color <color> Change color the Acid Rain.
/extremeclime events start <event> Change color the Acid Rain.
