Third Law Black Magic

[Leatherneck]

How would you do Black Magic spells for manipulating people work in DFRPG?  Are they placing an aspect that can be freely tagged, similar to the Addictive Venom?

[MijRai]

I'd say it is more likely you have to inflict a consequence or Take them Out in order to manipulate them later. No free tags besides the first either, unless you get a Power to augment it. The GM should actually be doing a number of the Compels on the afflicted, so you shouldn't have to pay much.

[DFJunkie]

I think both approaches are valid.  The OP's idea would be for quick and dirty compulsion that might last a few minutes and then fade while the second option could either implant a more lasting compulsion by twisting or replacing one of the victim's existing aspects or creating a full-blown thrall by twisting their high concept.
