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.

⚙️ 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
