I've decided to hold off on the radiance and play with deception first, based on advice from several people.
Just started to TR and got stuck on abilities.
The main point of going Drow would be to maximize Int, but if I set Int to 20, I am stretched on the other abilities. I end up with either 10 17 12 20 8 10 or 8 17 13 20 8 10. The Con is lower than I would like but I need Dex at 17.
If I keep Int at just 18 then I can have 10 18 14 18 8 10, much better balance with more Con and Dex. But in this case I'm essentially squandering the +2 Int and gaining almost nothing over say, going Halfling. The hobbit equivalent would be 10 18 14 18 8 8, making a difference of just 2 Cha points.
