[DF] "But I'm a (half) angel!"

As far as their Advantages allow - I would say if someone wanted to make this an important character element, take Social Regard or Reputation. Be generous with letting the player take these things if they want to spend points in that direction, but ultimately the player decides if they want them and they will not be freebees.

Ultimately, being put a pedestal is not always a positive. People might hold celestials to unreasonably high standards and react badly when those are not met.

People know celestials always detect as good - it could make people more suspicious, because you can't actually determine their moral outlook in the usual ways.
