I will note this, I don’t really know if I will be able to make a good map. Maybe a hex-based worldmap, or a more symbolic map that shows main locations and connections between them + how long it may take to move (I was thinking something like map from Mystia Izakaya).
About spell cards, I am not quite sure if my current implementation is good or not (they are mostly “cosmetic” for players without optional rule, more of a detriment to players with optional rules, and are practically custom spell for NPCs), but I hope it may help for balancing somewhat somewhat, since NPCs automatically lose the battle if they spend all their spell cards, and DM can, in theory, limit amount of spellcards (like exclude more powerful ones) to make an fight against high CR enemy possible (story-wise, high CR enemy may go a bit easier on player’s character, and while not truly defeated, must admit defeat because spell cards are defined in advance). I plan making all bestiary characters have amount of spellcards loosely tied to their in-game difficulty.
Also, if my Spell Card battles is confusing, I may try to reword it? Story-wise, it’s a bit vague in canon too, but the way I tried applying it to gameplay may leave confusion, since player and NPC Spell Cards are practically separate gameplay mechanics.
About discord - I will probably make one in some time (though it will be extremely empty, especially at first), but I think I will also enable forum-like community posts on Itch too. The only issue is that your current comments on this page will likely disappear, since community forums replace comments.
