Severian Skills, Kit, and Mindscapes

Severian's CRIT DMG increases by 60%, and his DMG increases by 25%. If there is another Wind character in the squad, his DMG increases by an additional 30%.
When Severian uses Basic Attack: Swift Edge just before being hit by an enemy attack, he can dodge the attack. If he dodges it with any of the first three hits of his Basic Attack, he automatically launches Basic Attack: Raging Whirlwind. If he dodges it with the 4th hit, that Basic Attack's DMG Multiplier and Daze Multiplier are increased to match Basic Attack: Raging Whirlwind.
When Severian enters the battlefield, he gains 2 stacks of Shadowflash. This effect can trigger once every 180s in Investigation Zone mode.
When Severian has Shadowflash and is not invulnerable, if he is hit by a non-Control Skill enemy attack that he fails to actively dodge or parry, he consumes 1 stack of Shadowflash to automatically dodge the attack and launch Basic Attack: Raging Whirlwind.
Successfully dodging an enemy attack with Basic Attack: Swift Edge, automatically dodging an enemy attack with Shadowflash, or directly dodging an enemy attack all count as a Perfect Dodge.
Shadowflash can stack up to 2 times. If Severian gains Shadowflash while already possessing maximum stacks, he gains 1 stack of Windborne instead, and the next Basic Attack: Swift Edge is enhanced to Basic Attack: Raging Whirlwind.
