[DF] Devil power help

[b-dog]

In my Mythic DF world I have both demons and devils. Demons are the more generic evils of the infernal region while devils are Abrahamic in origin. So while the more generic demons desire to kill and plunder the devils often enjoy tempting and subverting God's Creation in addition to general mayhem. The devils were once angels that chose evil instead of good and so for this reason they are able to influence others to choose evil as well. The powers that devils have are to be able to find out the weaknesses that a PC has such as as Greed, Bloodlust, Pride, etc. and then deceive the PC with lies to make the PC act out in a way that their Disadvantage comes into play.

Here is an example: A Wizard and a Knight encounter a devil in a dungeon. The devil sizes up that the Wizard has the Greed Disadvantage and from this information the devil comes up with a lie where he says to the Wizard during combat that the Knight has stolen some gems and jewels from the Wizard. The Wizard must make Will roll from his Will with overcoming Greed which might be say 12. I feel that Resistance to Evil powers would apply to the roll if the Wizard had it. If the Wizard fails his Will roll then he will become obsessed with the fact that the the Knight has stolen his treasure and will try to retrieve his treasure during the fight with the devil.

If the Wizard had Berserk or Bloodlust then the Wizard might very well begin attacking the Knight out of rage that his property was stolen.

I am guessing that this power of devils would be a form of mind control but it would also target the Disadvantages that a PC has. A devil could tell a PC with Alcoholism that there is ale in a barrel in another room and then the PC would have to make a Will roll based on his Disadvantage Will of Alcoholism to resist stopping combat to go and drink ale. The devil could also create ale for the PC to drink and then the PC would have to resist or stop combat and drink the ale.

So I am curious about how to set up a power like this for devils. Thanks for your help.
