Can anyone please enlighten me on how I should understand the following quote from RoP:D page 100:
To sense affiliation on a faerie with might 15, would the ease factor be 9 (6 + 15/5) or 15? Or 10 (9 + 1) since you have to "beat it by 1"? And to get insight about the faeries power, do you need to roll 20 (15 + 5)?
Hmmm given that normally a roll only need be equal to the EF, it might indeed be easier to think of the it being 10, but there may be factors I haven't considered as yet...
My reading is on a 10, you realise that supernatural creature is aligned to Faerie, and if you roll 15+ you get some idea what powers (ie active supernatural effects listed under its statistics as powers) it can do.
Generally, when in doubt, I aim for the order of operations which results in a lower number, because it makes the ability easier to use and more likely a player will have their character pursue it.
I agree with Ben (and I think I may have written it, way back when).
If I had to change it, I'd drop the "beat it by 1" bit. You make the EF, you can tell what realm the beastie is aligned to. I like that you don't need to penetrate, it being a divine power and all. I'd also change it to "if you beat the Ease Factor by 5 you gain some insight". Oh, and I'd replace the "creature's magic resistance" in the formula with just "Might".
