The Polarfreeze Defender was the holiday Familiar for the Crystalline Gala event that took place in January of 2015. The easiest way to obtain this Familiar was to Gather up 35 Eternal Snow currency and spend it at the Festive Favors booth while the Crystalline Gala was going on. The Eternal Snow currency would randomly drop if you selected the “Ice” Flight when you did your gathering.
The Polarfreeze Defender is one of the bear Familiars that are featured this year. Last time, there were Sprite Familiars. If you didn’t get the Familiar while the holiday event was taking place, you will have a more difficult time getting it. Try the Auction House.
