[Sitting here wearing my Zagreus t-shirt]

I feel like any of these characters would be great for pumpkinhollow, though I personally have a lean towards Zagreus. It's a horror-comedy which I think Zag is perfect for, and one of the game's mechanics involves dying repeatedly which is his specialty. Victorian gothic setting, spooky goofs, horror and drama!

To touch on your prefs: No nerfing required unless a power is game-breaking, extremely PVE with a collaborative mystery to solve, highly CR-focused. The AC is flexible--- you technically can just check in if you need to but activity is incentivized by way of being the only way to earn in-game currency.

Hope you'll check it out!
