It seems that activation of Bladewind differs from usual.
Usually, the Celestial Power is caused only by the attack by the skill to which it was assigned. However, when Celestial Power is assigned to Bladewind, Celestial Power is activated regardless of the attack of Bladewind.
For example, when assigning the Falcon Swoop to Bladewind, if Bladewind is activated, falcons will bolt out when attacking the target outside the effective range of Bladewind with a gun. It seems to treat the Bladewind as a passive skill, is it intentional?
