Three-Eyed Warlock
These warlocks have a third eye located in the middle of their foreheads. They only reveal their third eye when pursuing a victim, so they can appear as normal persons. Their third eye emits a deadly laser, which they use to burn holes in their victims' foreheads, killing them.

The Truth Spell:
For those who want the truth revealed,
Opened hearts and secrets unsealed.
From now until it is now again,
After which the memory ends.

Will hear the truth from other's mouths.
