Rising Toxicity

Rising Toxicity introduces a toxic fog that rises over a set period of in-game days, forcing players to take to the skys to survive. This mod was designed to take advantage of Create Aeronautics (Not Required) by encouraging flying bases.

Comment if you like this mod, and I will add additonal content.

⚙️ Mechanics:

Toxic fog rises over time to a set height (default 20 days)
Exposure builds in toxic air without a mask → damage at 100%
Masks prevent exposure but consume air
Masks fog up over time, reducing visibility and forcing you to surface
Air tanks refill mask capacity
Passive mobs take damage; hostile mobs are immune (Villagers, Wandering Traders, and some others are also immune)
Non-immune mobs can't spawn in the toxic fog
Fully multiplayer compatible
Configurable heights, timing, and progression via commands
Many config options for color, opacity, etc

⚒️ Items:

Gas Mask (Tier 1) – 1 tank capacity, 10 minutes of air, fully fogged at 10 minutes
