Void sickness

Maybe if your travelling in the new caves and go under -40 you could start to experience something called void sickness. Void sickness could make players nauseous, weak and maybe even have mining fatigue for short periods of time (maybe 30 seconds at a time) it could be added to remind the players of the previous depth limit of 0. Also it could make going down in the caves more dangerous for the higher amount of ores that are available and sort of balance it out. It could also not be curable by milk which will give you the opportunity to add a new potion that prevents void sickness it could last for longer periods of time (the basic could be 15mins and when you add redstone it could be 30mins). It could be crafted with loot that you find in the deep dark chests (not from the warden) it could be a skulk patch or something. The potion could be called void protection or something (I’m not too good with names) thanks for reading this.
