The Caster heroes are slinging spells, and one particular caster is feeling extra cool. Completing "The Frostfiend Cometh" questline will allow you to unlock the new Frostfiend Icepick skin. In addition, all Casters get the Spontaneous Cover passive, which allows them to generate an Aegis Shield after taking any damage. The other event quests pay out event tickets which can be spent in the shop for fabulous prizes!
