I live in constant fear when i'm in the nether.
I try to avoid large open spaces in favour of small open spaces to avoid ghasts.
Also the new changes to lighting, where if you're in an area of low light your view distance is reduced, makes it even more dangerous. Also it doesn't make sense.
Why can i not see something giving off light in the distance unless i'm standing near a light source? Really it should be the opposite.
My only solace is the zombie pigmen. They leave you alone if you don't attack them.
They're like slightly more dangerous villagers.
Also yeah, wither skeletons are scary. Only have to kill, what, 1198 more to get the skulls we need to make a wither?
