While looking through RoP:F I found some odd things about Characteristics. First, as they are not human, they don't inherently have +/-5 as caps. Second, I am aware of values going outside the normal bounds based on Size, and I'm not worried about that. Third, there can be confusion when involving faerie animals since we're supposed to base things off of the rules for mundane animals. But if you're trying to account for everything, which is done entirely via Virtues in RoP:F, what are you supposed to do past +/-3? How about past +/-5? Here's what I've found:
Improved Characteristics (ArM5 Minor Virtue): to +3
Great (Characteristic) (ArM5 Minor Virtue): from +3 to +5
Poor (Characteristic) (ArM5 Minor Virtue): from -3 to -5
Weak Characteristics (ArM5 Minor Virtue): to -3
These get us to +/-3 or +/-5 seemingly fine. But how do you get beyond +/-5?
Improved (Characteristic) (RoP:M Major Quality): beyond +5
Reduced (Characteristic) (RoP:M Major Inferiority): beyond -5
Now we can get beyond +/-5, but these aren't really Virtues or Flaws, so faeries shouldn't have access to them. So how do we handle things? Let's look at some of the cases from RoP:F.
Gorgon - Perception +6. It has the points to get to +3. So presumably its power Dozens of Eyes gets it from +3 to +6.
Morma - It only has 3 points of its 7, but it doesn't have Weak Characteristics.
Lesser Nymph - It has 7 points.
Ghula - Presence +5. It has the points to get to Presence +2 and one more toward Presence +3. It doesn't have Improved Characteristics, nor does it have Great Presence.
Glanconer - It has 16 points, the extra 9 of which have been covered by Improved Characteristics x3.
Fachan - It has 7 points.
Knight (minor) - It has 7 points. But it also has Improved Characteristics x2. Where did the extra points go?
Valkyrie - It has 7 points.
White Lady - Int +4, Pre +4, 25 points up to Int +3 and Pre +3. 6x Improved Characteristics cover the points, and 2x Great Characteristic cover the +4's.
The Privy Counselor - It has 13 points, the extra 6 of which have been covered by Improved Characteristics x2.
Licho - It has 7 points.
Triton - It has 7 points.
Selkie King - It has 10 points, the extra 3 of which have been covered by Improved Characteristics.
Faun - It has 16 points, the extra 9 of which have been covered by Improved Characteristics x3.
Satyr - Qik +4, 13 points up to Qik +3. 2x Improved Characteristics cover the points, and Great Characteristic covers the +4.
Orm - Though not of human shape, it should be noted they have "Increased Characteristics," whatever that is.
So, while most things fit, we're left with a few things that don't. I guess we can go past +5 using a constant power as with the Gorgon; it better be a big power since that's more than two Minor Virtues would get it. Why are the points off for the Morma and the Ghula, and why is the Ghula able to get to +5? Is there something called Increased Characteristics? So how are we supposed to handle +/-6 and beyond normally?
My current thought is that the easiest would be a Greater Power, bought as a Major Virtue of course, identical to the Major Quality Improved (Characteristic).
