Cursed/Darkness, Creeping Darkness

[Kragtor]

Based on the combat log, it looks like the Cursed Darkness line isn't multiplying the base damage things take while in darkness for every ability. I should have 124% bonus damage to things in my darkness, based on how it's worded in the skills. It's only showing a bonus of 31%. Is this bonus supposed to be only for the skill itself? If so, why does the skill that does no damage at all have this bonus on it?

Also, is Creeping Darkness supposed to do no damage half the time? Is Dark Torrent supposed to miss, despite just being a beam type ability? I've seen stuff walk right through the darkness with no damage, and i've seen the beam miss stationary targets; log says it fired, no damage registered(not an immune target).

Thanks for any help with this stuff!
