@"Livin in Sim"
Completing the Freelance Botanist aspiration gives the Sim the Naturalist trait which protects the Sim from fires with stoves, grills, and campfires. The sun can still kill a vampire.
I'm playing a game generated Grand Master Vampire who got the Love Outdoors trait. He's always outside grilling food. So far, he set his stove on fire which destroyed his kitchen while he panicked and ran outside. He went on a camping trip to Granite Falls where he tried roasting marshmallows. He burned his arm just lighting the fire. I think he really needs that reward trait.
