The wither storm is hard to see during the night, which hinders your ability to know how far away it is. my suggestion is to add a colored outline(possibly purple or blue) to the wither storm's distant renderer during the night. that's my entire suggestion.

purple outline would be best. also a good idea to add purple lightning (as seen at the start of episode 4)

that's what i'm saying, at the moment it's ever so slightly darker than the night sky if you zoom in on it. but not everyone has spyglasses or zoom mods.

This was attempted during development but didn't work overly well. I will be willing to look into it now however.

Implemented in 2.2/3.2
