Dispelling Powers & Conflicting Effects

To dispel a power of a creature of Might, you treat the power as if it was a spell of a level equal to the creature's Might. Cool.
What about a power wielded by a character, through a supernatural ability? I read what the Penetration is, but I couldn't find what the level is for dispelling.

Also, what happens if two spells of with conflicting effects affect someone at the same time? Say a person is made happy by Magus A and then made sad by Magus B, both with a Sun duration ReMe spell. Now what?

  • level of ability x5
  • IMO, the one with most penetration win. It gives preseance to the effect with lowest levels, all other things being equal and apply the right sentence: "for each task, a tool".
