Haunted enemies look like old damaged statues with ectoplasmic flames coming from their cracks.
Enemies with this trait have several abilities.
The first one is 'soul.' After death, they are reborn as souls with their own stats and abilities. However, the enemy can be killed without resurrection using the conjure ability.
The second is 'attack variants.' Most enemies with this trait have two or more attacks that alternate with each other. Different attacks have various damage and effects.
These enemies appear in a new story chapter called 'The Lost City' unlocked after beating the Infernal Tower.
