Negitive energy afinity and incorporeal touch.

[Cerwin]

Can a dhampir be damaged by a wraith's incorporeal touch attack? I'm running a game which one of the bosses is a wraith and one of my players is a dhampire. I'm worried that the party will just let him solo it and wait outside the room til the fight is over because the only attack that a wraith has is a negative energy attack. I'm hoping to find a RAW way to make this fight not completely trivial. Any help would be much appreciated.

The Wraith's incorporeal touch has two parts - 1d6 Negative Energy damage and 1d6 Constitution Drain. The Constitution Drain is not a negative energy effect because it is never described as such - it's a separate power, and will work on things that are immune to negative energy effects but not to ability drain.

(So, it's useless on other undead, but still helpful against near-undead like Dhampir. ...Although the negative energy will still heal a few hit points. XD)
