Weird title but uhh..
Since there will be an outside now, and I'm assuming there will be a day and night cycle, I suggest a trait for the vampire that makes it to where they take burn damage from the sun.
Ofc it would be a pretty hardcore negative trait, so ofc there should be ways to counter the beams of the hot sun :)
I mean this trait could already be a possibility, but just in case I'm making this suggestion.
Who knows what crazy ideas this man has, he could add something as crazy as an umbrella 😳
