Warhammer Fantasy

A concentration spell. The caster designates a creature they see within range. The creature must succeed a charisma saving throw or be enthralled to the caster's will for 1 hour. At that time the creature's eyes turn to the color of the caster. The caster commands the creature telepathically and may even speak through their mouth, forcing them to act as they will. An insight check done on the affected creature will reveal that they behave excitedly and are perspirating. The affected creature will attempt to break free when they are faced with appalling or dangerous commands. The caster must keep the target in line of sight, if that is broken, the spell fades away. The whole ordeal however is quickly forgotten by the target, who returns to behave as usual if a little bit confused.
