This month we created a snow flurry creature/effect combo and a much deadlier Snow Fury creature who could easily be mistaken for the former.
The Snow Fury is an elemental creature of blinding snow and deadly cold.
It is almost impossible to hit or hurt, except with fire.
Wyldhunt is working on a rather clever AI for it, as well.
Unfortunately, we also committed to creating a "foggy breath" effect for version 2 :-P
I just don't learn ;-)
