Gaea would need to keep her armor up all night with Wild Fire as a roommate, it's not just high temperatures but actual flames she cannot control when asleep.<br/><br/>I imagine its better to make a fireproof room for npc comfort rather than a fireproof box...I would say if your character has at least 25 energy defense and 15 recovery then she can be Wild Fire's roommate (or some combination that wouldn't risk being burned alive as she slept)
