If anyone can point me in the right direction without a full spoiler I'd be grateful.
I'm trying to find the relic using the Braindance in Yorinobu's apartment. I thought I'd searched everywhere but clearly I'm missing it. I assume it has to be within signal range of the girl. I'll keep going but I got a bit frustrated with it earlier.
Did you cycle the filters between visual, thermal and audio? The signal range for visual and thermal are LOS, and a couple can be some distance away.
You need to look for a cooled location, which is stable. Some are not cool enough, some are likely to be disturbed/change temp. As Evie moves around the flat she can pick up new thermal 'hits', so you need to wipe back and forth as she follows YA about or steps out of his way.
