Approach ghost room with incense primed and lighter ready to go tier 1 range covers 3 meters which is plenty for basic protection but higher tiers give better safety margins at 4-5 meters, depending on upgrade level. Light it only when ghost is closing in and remember the prevention window lasts 90 seconds except for spirits at 180 and demons at 60

Keep track of hiding spots near exit routes since youll need quick access when things get dicey. Smart to coordinate with teammates because multiple incense dont stack and just waste resources, especially during longer investigations. Position yourself between ghost and escape route when lighting up makes a huge difference in survival chances

Good to maximize that protection window by lighting near doorways or choke points where ghost movement is predictable. Tier 1 works fine for most situations but if youre tackling bigger maps, higher tiers give extra breathing room with their improved range and ghost control effects. Just remember matches or lighter are essential cant do much with unlit incense when things get rough. Wait for ghost to get close before lighting no point burning resources early when you could save them for when you really need that escape window
