Mesmerising Mirror

The Mesmerising Mirror is an arcane relic of the Chaos God Slaanesh that can be deployed by the Dark Prince's servants against their foes.

A Mesmerising Mirror is a cursed artefact of Chaos, sent from Slaanesh's palace in the Realm of Chaos into the mortal universe to ensnare the unwary. Those who manage to tear their gaze away feel a ripping tear in their soul -- but those who do not suffer an even worse fate.

Their life essence is drawn from their body, trapped in the mirror forevermore as a plaything for Slaaneshi daemons.
