I still don't know how to call it. (Still looking for a fancy name)
Basically it's like the chorus plant except it is found in the nether.
There will be Nether* plants, Nether* flowers, and the fruit itself.
Eating the fruit will restore 4 hunger and 2.4 saturation (Like the chorus fruit).
The effects when eaten are:
Nether* Fruit ingestion: exactly like fire resistance except it only has a maximum effect time of 30 seconds
In rare cases you will be set on fire instead
Each Nether* fruit you eat will give you an extra 5 seconds of Nether* fruit ingestion effect with a 2 second cooldown before eating it again.
Nether* flowers and nether* plants only grow on soul sand regardless of light level.
Nether* flowers and plants behave exactly the same as Chorus flowers and plants
* - Still can't find fancy name
** - Probably not a great idea
