[1.7.6] Creeping Darkness doesn't block monster LoS

[Doctor_D]

After 16+ hours of gameplay and testing this with 5/5 Creeping Darkness + Adept + mastery boost, I am fairly certain that monsters ignore the LoS-blocking aspect of this in 99.99% of time entirely -
making this iconic but mediocre ability tree pretty much useless.

I was told on discord that it does technically block LoS, but in a way that is incompatible with how LoS in general works. I do unfortunately not know the technicalities behind it.
