Well, those hadn't even been considered.
But THIS one has been thought through.
MythPower: Dyssebia's Defiance(Rough Draft)
The ability to channel Dyssebia's command over the essence of irreligious impiety and godlessness
You cannot be directly contacted or affected by ANY divinity, regardless of pantheon, and you can psychically perceive, communicate with and compel those who are particularly sinful. In addition, if you compel them to do something evil or sinful, even those with mental immunity cannot resist (as long as they believe in no god, or are very sinful).
Good:
Perceive and induce sinfulness and disregard for religion
Psychically perceive, communicate with and compel the sinful/irreligious
Immune to any direct divine influence
Bad:
If you are actually an atheist with this power, permanently negates all other divine powers
Cannot negate it to gain other divine power
Guarantees certain damnation (if taken by atheists)
