You’ve done a pretty good job of creating a special playbook given your supposed lack of experience with the system! I call it a “special” playbook because basic playbooks in Blades generally don’t have abilities that directly build off one another or that would apply only to that particular playbook. Remember that players from other playbooks can choose these abilities, too, by the rules and design them appropriately.
Oh and shock absorbers mentions prowl “checks” which are not a thing. Players only roll. I think I know what it is you mean but the wording seems strange when applied to Blades.
