The race I want to make is basically a dryder with an umbral dragon torso, 4 arms, wings, and clockwork parts. What would the spell-like abilities and bonuses.
It would seem that the spell like abilities and bonuses would be what you wanted them to be....
If you gave us more like a role in the world/adventure you wanted them fill and what sort of challenge rating you think they should be we might could offer some suggestions.
Of course Darkness or Deeper Darkness as a spell-like seems like a no-brainer.
