I won't lie, I'm kind of disappointed. Between this and the core book I was hoping for some kind of Knightly channeler playbook, or otherwise one that expresses martial skill through their Astir one way or another. But every playbook is some kind of spellcaster aesthetic, none of them suit how I approach a fantasy mecha game, or more generally allow for Mecha genre tropes.
The game otherwise is very good, I like it a great deal, but even with this supplement there's no playbooks that engage me.
