Title: Wraith

Describe wraiths here
An non-hostile monster that impairs your vision and spawns shades in considerable numbers to surround and attack you. It has a huge amount of health and is very fast to make the encounter more interesting.

I have never pushed my almost non existent coding abilities to such an extent and I fear that I could have broken something important, I compiled the game and everything seems to work well, but I will revise this super extensively if I were you.
