Numbness Effect

The numbness effect would do the following (probably easy to tell by the name) - It wouldn't show your health so it's hard to tell if you got hurt. This could be useful if you have a splash potion of it during combat it would make it hard to track what health you have giving the other person an advantage - Not showing ticks of damage. This would also make it accurate because you wouldn't not just be able to tell if you are hurt but you can't feel it either - Powder snow can numb you if you are in it long enough - Lastly, numbness II would make your vision slightly blurry
