The Below World Update (Part 5): Hazardous Atmosphere

This site only allows you one idea per post so I will be chopping up my ideas for The Below World Update into multiple posts.

What is the Below World Update?

The Below World Update is my take on the nether revamp. In my version, my goal is to give the player reasons to think of staying in the nether or continuously venturing deeper. These include things like:

1. Unique Hazardous Nether Environment
2. New Mechanics
3. New Structures
4. New Mobs
5. New Treasures
6. New Goals For Player
7. Tweaks To Existing Mechanics

I don't know if you aware of this but the overworld has different looking biomes. This post will suggest a certain category of biome which could exist in the nether.

This category would heated biomes. These biomes are too hot to be traversed without assistance. While in these biomes the player will take damage over time (like poison). Drinking a fire resistance potion or having fire protection will just cause the player to take damage less often.

To truly stop the damage you could find an equitable item in the nether or brew new a potion.
