To be fair, is both on a lower cooldown and is capable of dealing more damage than Air Blast (Steel Tempest can crit, Air Blast cannot). Its knockup is also more disruptive than Air Blast's knockback, and while Air Blast is Rheya's only ability capable of dealing physical damage, also has his ultimate. The only advantage my Air Blast has is that it can apply on-hit effects to multiple targets instead of Steel Tempest's one.
