Phasmophobia

There are 3 pieces of evidence to collect for Hantu if you are playing on Professional or below which are:
Ultraviolet
Ghost Orb
Freezing Temperatures

There are also some other attributes to this ghost which will make it easier to notice, especially when hunting. For one, its speed is entirely based off of the temperature of the room it’s walking through, so if the breaker is turned off (which a hantu will tend to do more often), it will be quite fast.
Secondly, there is also a chance that when hunting, you will see its breath, the same as you would for yourself when in the ghost room, so if you see this, then you definitely have a hantu on your hands.
