I really like the space you created with a sorcerer huntsman designing all sorts of odd creatures just for the perfect hunt. The subtle little nudge of the stone creatures in the garden and handing players stone to flesh potions to just… “see what happens” is great as well. The basilisk-bell trap is a favorite to, just really clever.
On the other end I would have questions on how to run certain aspects of this module. Cedric is clearly the primary and only antagonist in this module (unless players decide to get creative with stone to flesh potions :))so I feel we need to know some more about him. How does he hunt, what tactics does he use, what trickery mundane or magical does he use to engage his prey. Does he use his own creations to hunt (for example maybe he has a creature with a bloodhound head for smelling things out and a cheetahs body for quick tracking and attacking)? Despite his brutal inventiveness is he an honorable man who admits defeat if you best him in the hunt or will he backstab you after “admitting defeat”. As the primary antagonist, I think you could devote an entire page talking about him so GMs can get a feel for who he is as a person and how he hunts. A GM can come up with their own clever ideas too but having something to play off of on the fly is helpful to the GM. Fleshing Cedric out, I think will make the space “whole” if you will. Right now we have this really interesting manor but I don’t feel like I am in danger from Cedric. Make him dangerous, a force to be reckoned with, he is a magic wielding hunter after all. Your players should fear this man as the perfect hunter. Also it might just be me but I saw his HP was 10. Reading that and following Knave’s rule set I’m pretty sure this guy goes down in 2-3 hits so not even a single round. Probably pump that number based on you current HD 7x4 at 28 HP with level 1 characters, now he’s a little more terrifying. In fact as primary antagonist he should have more than that as players are going to focus fire him. That or give him additional help, summoned creatures, a magical damage resistance barrier, mundane weapons don’t hurt him just something to resist those damn murder hobos onslaught :).
Also I read V1.1 but I didn’t see descriptions for the spells found in Cedric’s room. Are there still sheets missing as I only saw 4 spreads?
For the portal space, perhaps more info as well. Maybe Cedric hunted a mage in there and the mage is still living in there as he tricked Cedric with an illusion to think he is dead. Feels like there could be dreadful creatures living in that space but we only get a short description about what it is and its concept as this manipulatable hunting ground is SO COOL.
Last item I’d add and it’s super minor. If the module is made for Knave I believe the valuations that Knave uses is in c rather than gp. I did the same thing at first when writing up my module lol. Probably not an issue and especially if you want to leave it open to anything OSR rather than just Knave.
