Why on the earth does walking on snow dispel the invisibility magic?
I surely understand that even when invisible you still leave footmarks behind,
but what I dont understand is how does walking on snow affect your magic?
If I have casted an invisibility at myself and Im walking to a cave for
bearhunt, I assume I still have the invisibility up when I reach the cave
where there wont be left any footmarks. Who the heck cares if I left few
footmarks behind on outworld plains where probably no-one will even see those
marks?

Remove this "realism tune" which actually aint so realistic, please.
