The first step to properly using this tool is knowing that you need a lighter to set the Smudge Stick alight. If you’re playing alone, that means you’ll need to pick up both items; in multiplayer, ask your team if anyone’s got a light.
You can also light one of these items with an already-lit candle, which is helpful if you can’t find a lighter or are low on inventory space.
Once it has been lit, it will begin to smoke. It may take a few attempts before the stick ignites properly. Now, you can hold it in your hand, or you can throw it on the ground. It will dissuade a nearby ghost from attacking you too often. It can also dissuade a ghost from moving. Either way, you’ll be able to calm nearby spirits.
While it won’t be an objective every time, you will often find cleansing as a mission on your truck whiteboard. Clearing this task is a great way to keep yourself safe during your ghost hunting forays and to make a little extra money.
