@stonegod: Just in the process of leveling Ashlyn and I just want to confirm that the Sun devotion feat from Complete Champion (pg 62) is okay. I assume that it's fine since the Complete series is approved material, but I'd rather check. The feat would fit Ashlyn rather well, particulary since she gains the sun domain from the 3rd level of the Knights of the Raven PrC, thus making this a very cohesive choice from an RP perspective.
Here's the Sun Devotion feat description:[sblock=Complete Champion]Sun Devotion [Domain]
Your weapon blazes with the power of the sun.
Benefit: Once per day as a swift action, you can cause one of your melee weapons to glow with the power of the sun. The illumination radius is the same as a torch, but the light is true sunlight and affects creatures within a 10-foot radius as such. This effect last for 1 minute.
While your weapon glows, it deals an additional 1 point of sacred (if your deity is good or neutral) or profane (if your deity is evil) damage per character level you possess to any undead it strikes.
Special: You can select this feat multiple times, gaining one additional daily use each time you take it.
Special: If you have the ability to turn or rebuke undead, you gain one additional use of this ability for each daily turn or rebuke use you expend.[/sblock]
