Frost Atronach is a boss on Slender Fortress and was introduced in the Christmas update.
The Frost Atronach is one of the different kinds of Atronach, another for example being the Fire Atronach which was in the Lunar Republic Slender Fortress server. It looks like a tall humanoid made of Icycles, and makes a sound that sounds like something is in the process of being frozen. It also has giant icycle hands, legs and a ginormous icycle body with a significantly smaller icycle head.
In Slender Fortress Edit
Frost Atronach is in Boss Pack 13. It is a fast presistant chaser who Insta kills, it also is hard to hear because of the freezing and frosty sounds being quiet.
