Alternate appearances for this hero. A costume is purely cosmetic: it shares the hero's stats, skill, and passive.
Niven, having left the snow-clad mountains and donned a blue mask, has hidden herself within shadow. Carrying the resentment of the Frost Elves buried in her chest, she has taken on the task of cutting down, one by one, those who disturb Nospher's silence. Tempered by wall-facing training, her fingertips do not waver, and the arrows she looses fall as quietly as frost, they say.
Niven, who has forged a contract with an ice spirit, beats his wings just once. That alone is enough to freeze the air around him, leaving a trail of cold frost along every path he passes through.
