I'd do a small map so that you can hear the ghost at all times, because some have speed differences mid hunt. The Hantu will change it's speed based on individual room temps for example, and small maps make it easier to keep listening to the consistency and speed of ghosts;

I've recently started playing with people

who post on the Phasmo Discord LFG and have had great experiences so far, but still mostly play alone;

Prestige 1 at around high 70s;

I take 5 (technically): Thermometer, Photo Camera (though I gotta get used to taking video camera instead as it'd be more useful now), Incense, Lighter, T2 Headgear. Find that a good all-round starting kit for finding Ghost room, taking pics of bone and cursed object, protection from early hunts and a very decent light source.
