Hello guys, Overlord Aqua@2 here, and I'm gonna tell you an effect combination, where I called "The Ultra Blindness Effect". As I experimenting some effect combinations for potions and make a cool name on it for making an advenure maps, this effect combination is about Blindness + Night Vision = Ultra Blindness Potion. Be careful, if you got blind, don't take some Night Vision Potion/Effect, I already experience this effect. As you notice, in ordinary blindness, you only see 5 blocks radius around you:



However, in blindness with night vision effect, this is what happen, you're fully blind even the closest mob, you can't see them. (see the Voxel Map on the upper right corner)
