Hunting Frostallion, the Level 60 legendary Ice mount in the Land of Absolute Zero? It's the snow-white flyer that converts your ridden attacks to Ice, and the trek to it is a frozen deathmarch, so pack cold protection. Below: coordinates, weakness, drops, and the endgame fight plan. Here for the coords? First card, right below: -354, 508.
Frostallion is found at Land of Absolute Zero (snow, NW), east of the teleport, at coordinates -354, 508. The nearest fast travel point is Land of Absolute Zero, so you can be on top of it within seconds of unlocking it. Bring cold gear or a warm food buff, because the trek in will chip your health before the fight even starts.
Frostallion is Ice, so lead with Fire damage and you'll carve through its health bar fast. Reliable picks: Arsox, Wixen. Pack a bow or firearm too, since poking from outside its attack range beats trading hits up close.
