Quick and dirty mechanics for 5+ Appearance? For any character with an Appearance of 6 or 7, any mundane creature viewing the raw radiance of pure physical perfection must roll Willpower or be stunned by the beauty. Difficulty is 4+1 for each dot over 5 (using Second edition rules) or Difficulty 2+1 for each dot over 5 (using Revised edition). Any character with an appearance of 8 or 9 will have a much stronger effect than those whose beauty is lesser. 8 or 9 Appearance scores will cause low-willpower victims to immediately fall in love/lust/fascination with the character. Higher willpower victims will react with an immediate and uncontrollable Frenzy. They will flee from the character, fighting to the death to escape the unnatural beauty. A 10 in Appearance will automatically begin inflicting lethal damage to the viewers, at a rate of one per turn. This damage can not be soaked, as it is not physical, but psychological. After 5 damage is inflicted, the victims will gain a permanent derangement, and immediately Frenzy in an attempt to escape.
Or at least, that's what I've always used. A 5 in any score represents the pinnacle of human perfection. Batman has scores of 5. A 6 is, to me, as far removed from a 5, as a 5 is from a 1. And a 7 is twice that of a 1 to a 6. When you're dealing with scores that are 5+ you're dealing with something that's truly super-human, and the game mechanics should reflect as such.
