Re: Comeliness based skills
As much as I like having COMeliness a chracteristic, I honestly don't think it lends itself to many, if any skills, that couldn't also be modeled with PREsence and PRE based skills that would get a complimentary COM roll to strengthen the effect.
I remember, I think it was in 3rd Edition, that Climbing was a STR based skilled, presumably because of the aspect of climbing that involves grabbing and pulling one's weight up. Starting in 4th, it became a DEX based skill (and clumbsy people do have trouble climbing, no matter how strong they are) but a STR roll could be complimentary.
I really think COM works best as a complimentary roll to many PRE based skills. But as a characteristic, it fits in with with the complimentary roll rules.
