Thank you! I probably agree - one of the nice things about designing for Blades is that the basics are really covered with the regular playbooks, so it felt like I could focus on thematic moves and let the player work out how to fill in the gaps! I partly designed this as a break from some more nuanced design work on my main project, so I deliberately didn't really hold back on what went in.
Adding this as much as a note for people who try out the playbook and because your comment got me thinking! I think there are a couple of niches where the Skeleton really shines. The first is as an information gatherer with moves like Bone Meal and Skeletons, Plural - you start with a decent prowl and it's easy to lean into that, probably focusing on the dark shadows of Doskvol perhaps with some lurk or slide moves. Read the Bones and Danse Macabre work really well paired with some whisper moves, to create an uncanny, skeletal magician. Lastly, you can of course go full nightmare with moves like Sentient Ossuary, The Devil's Backbone, Behind the Mask and then Sticks and Stones to resist harm - I think adding some Cutter into this too would be terrifying.
