Hero

Karsu

Duelist

The Finisher

Karsu fires a volley whose arrow count scales on Attack Speed, up to fourteen, each one applying Frost. He is area control disguised as a Duelist: at 5 range he never enters the fight, and a full volley slows an entire board at once.

What Karsu gains per rank

A hero climbs C → B → A → S — 3 upgrades in all. Every stat rises at the same rate on every hero, with one exception: the primary stat of the class rises three to four times faster. For Karsu that stat is Attack speed.
