Well, every character dies to a bad roll sooner or later. It just happened to be sooner in this case. :\ I honestly don't think anything was really wrong with Silhouette in terms of combat capacity, but I certainly understand your desire to build a sturdier character.
One thing that I note is that we don't really seem to have many divine casters. It's something the party has always lacked.

PS: I don't think items should work while within items; that gets strangely recursive.
