Puppet Master

Effect: Forces a target to obey the caster for an extended period
Range: Short
Defense: Skepticism
Resistance: Spirit or Earth
Cost: 4*
The caster now maintains active control over a target, for as long as the spell pool is dedicated. This spell is visible to enchanters and diviners, but is otherwise invisible.
The spell is a ritual and takes 2 actions to cast. It is opposed by the target's skepticism, with a threshold equal to their will. The threshold increases by 1 each time this spell is recast on the same target, and 1 for each full day the target is bound. This additional cost must be dedicated each day.
For example, Nebiat binds Dirk. He has a 3 Skepticism and a 4 Will, which means she needs 7 successes to bind him. If she succeeds, that number will increase to 8 the next day, and 9 the day after. She'll have to dedicate that part of her spell pool, and if she stops, Dirk is free.
