A dark spirit is a spirit that blocks the way to a door in Daemonheim. It needs to be banished using Prayer to enter the next room.
It will attack players who fail to banish it, dealing damage roughly 1/3 of the player's total life points.
The player's prayer level must meet the minimum level requirement for the specific door before being able to exorcise the dark spirit.
||A dark spirit is blocking your path.
||You exorcise the dark spirit.
||The gods snub your prayer, and the dark spirit attacks you.
