Maybe something like this. While Dex is PSS it would mostly stack Pre. It won't be grea dps, but it should be fairly surviable and has some decent utility. Not too many dps powers in Celestial, unfortunately. Could also go with Sentinel Mastery if you plan to fully charge Shadow Blast or Vengeance a fair amount and want more heals.

It deals with life and death. It works pretty good and does quite a bit of damage.
