The problem with trying to "stat" Silk in D&D terms is that D&D only has Strength, Dex, Con, Intelligence, Wisdom, and Charisma. If you're going to give stats to Silk, you need to create an "unbeatable overal coolness" statistic that goes to at least 100.
Sorry. In case you all couldn't tell, I'm a rather large Silk fan. And I don't mean I create a gentle breeze and look good with a kimono.
