I am starting to write an adventure for a murder mystery. So these ideas are just my thoughts currently
The problem I am having is finding a spell for mind control. In Advanced Heroquest there was a spell for Amethyst Wizards called Spirit Control. Maybe I am missing it but I cant seem to find one in my cards which can do the same thing. I dont have any 2nd edition books to look up.
Component: Stiffened Velvet Tube
The Wizard holds the tube to his forehead to form a third eye. With it, he may see into a previously unexplored area. Generate the contents normally. If there are any monsters present, the Wizard may choose one and control his actions. (This may not be a special character.) The creature may be made to open doors, move into unexplored areas (revealing them to the Wizard as it moves), attack other monsters (which will retaliate), or perform any other action which isn't alien to its nature (like injuring itself). The spell is broken when the Wizard takes an action, or the monster is wounded.
My idea is this.
There are the several party watch members played by the players, one would either be a player or a gm played one, but that would throw too much suspicion too early if gm controlled.
They have joined the city watch to pass the time, or maybe they heard of the murderers and wished to get involved. The murderers have always been found but have no idea why they performed the crime.
One of the players is actually the murderer (The murderer player is either under the wizard control or is the wizard himself.),
The mind controller is an Amethyst/Dark magic user who uses others to perform murders for him for either coin or some other reason.
The victims are either prominent citizens or just a random citizens. Since the spell doesnt need line of sight the controlled person never sees the caster.
Problems I see currently.
Why doesnt he control one of the other players and kill one of the others?
If I can solve the above problem, then its just a case of
How to trace the crime back to the party member? or do I not and the party member leaves the party and town. The crimes stop and they then put 2 and 2 together.
I have so much to work out still, but any help on some problems I havent forseen or solutions be greatly appreciated.
