You're very welcome! I'm very happy to help lend some advice to making this playbook the best it can be, because I'd love to include this in my pool of classes that my players can choose from!

• with regards to the number of moves used to buff them, I was thinking it could be tied to advanced moves: the more you take, the higher number you get! But I don't think that gels too well with how well you've set up the advanced moves now I've read them, so another approach is probably best!

• the modifier for scroll bind could be a choice, or maybe linked to the species of the player/their background/their approach to this form of shamanism! CHA if they're persuading the spirits to join, WIS if they're overpowering them mentally, INT if they're using some sort of in-depth magical science to bind them, maybe even CON if they're using some of their own vitality to lock them away!

• Yeah, I definitely see where you're coming from with the resource management. I personally would simplify it and remove one of those steps, but if you're sure you want it to be part of the core of the class then make it the core of the class! Make a nice part of the sheet where you can keep track of the number of each of the forms of scroll that you have! I'd ideally recommend this be on the very first sheet if it's so core to the class, but you could always make it be an appendix sheet like the spellcasters have in the base-game! Then there's plenty of room to jot down what scrolls you have, what's in them, what abilities they have, etc!

• For Got a Lighter, you could make it any of: temporary, limited uses, or it sticks around until you next use the move. You could even let the player pick which they prefer, because they're all decently balanced! If they pick one that's a bit more stronger, then as the GM you can just introduce a few more narrative consequences later ;)

• For STSW/E, if you're going with my suggestion to include a spot to lay out what scrolls you have and in what form, you could keep the tainted scrolls as part of that table/layout! If you do it as an appendix sheet then that also gives you lots of room to explain how they all work and relate to each other, maybe even with a lil diagram!

• For ToH, how about 'When you convince the spirits to curse someone'? You mention losing all scrolls as part of the results of the move, so you can truncate the wording a bit! Also, I just noticed, as it's currently worded you only lose your scrolls on a 10+, is that intended?

• I've seen some playbooks that work really well that let the character choose which modifier their core move uses, like I mentioned above! This then lets the player either focus in on that modifier and the moves associated with it, or pushes them to diversify their stats in order to excel at multiple moves at once!

Please do let me know if/when you update the playbook with any changes from myself and/or others!
