The Spirit Blade classes design is based off the Quincy which is a human who is able to sense and fight soul reapers.
The Spirit Blade classes weapons are the Blade weapons, despite them showing using a bow for their attacks.
The Spirit Blade class skills are generally based off abilities that are meant to inflict a series or set amount of high damage or are meant to aid in the battle with status effects like dodge rate increase. Like the other classes there are a total of 10 skills.
