your double is even spookier

Prerequisites: base charisma 23+, Haunting level 6, Deed (see Special)

Benefit: Your Major Image created by the flee the scene invocation counts as quasi real. It is no mere illusion and can attack once per turn, using a shadow copy of your weapon, either during your turn or as an attack of opportunity. It always makes touch attacks using your melee attack modifier (+4 for touch) and deals half of your Eldritch Blasts damage dice plus your Charisma modifier points of force damage damage. Because it is no mere illusion, enemies have no chance of disbelieving and true sight does not help either, an opponent can only defeat it by killing the Haunting or dispelling it.

Special: You have to have dealed the killing blow on an enemy while they was flanked by you and your double to take ths feat
