Fridge... is the most fun boss I've played since Frogmar.

That badboy requires teamwork.
No soloing can be done.
I tried soloing with tank elixir, and died.
Wolfling rushed in and the whole party died.
It requires at least 2 45s and a full party with 30+ equipment to kill, and even then some die.

I mean, it has massive ice aoe damage, can freeze, and can one hit kill with its melée.
impressive.
