Oath

Effect: Creates a binding oath between two parties
Range: 1
Defense: NA
Resistance: Spirit or Earth
Cost: 5
The binder blesses a willing oath given freely. So long as this oath remains unbroken the target gains the oathsworn perk (this can take them higher than 3 perks). The target is honorbound to pursue or defend their oath at all costs. If they fail, then the spell is broken. They lose the oathsworn quality and gain the oathbreaker flaw.
The oathsworn perk gives the target edge on all actions taken in association with their oath. If you swear to protect the minister, then you don't get edge while dicing with guards, but you do when trying to spot the larcenist who just evaded his best scanners.
The oathbreaker flaw prevents the character from ever having edge when dealing socially with anyone who is aware of the flaw.
