My wife and I run some Adventure Paths solo with a Tristalt character.

As another bonus we either add to an existing race or create a new one. For 30 (to get Fast Healing and some other stuff).
With her "Advanced Dhampir" she took an at-will SLA (Flight).

Now what would be some of the best uses for RP to buy?
Strong options I think are:
Fast Healing 1, Moon-Touched Damage Reduction, See in Darkness, Constant Spelllike Divination, at-will SLA, the fixed feat without prereq's and the Bonus Feat one.

Did I miss something?
What SLA (that don't deal damage) would you take? Flight or Dimension Door(Summoner list) will always be good options but are there others?
