Half-Breeds:
A) Mix and match. You get 1 Major ability, 3 minor abilities (for the humans, that's 1 extra skill point each), and 1 extra type of sight (DV, LLV, whatever). Have fun.
B) You can be a half-breed: Pick the major and 1 minor ability from a single race list, and then 2 minor abilities and the visual trait from another race list. You can also be a quarter-breed: Pick 1 ability for each race list, and give the visual trait from a race with a minor ability. Quarter-breeds are basically the same as (A), so half-breeds are recommended.
C) Use pregenerated races. Who knows, maybe your DM believes that LLV is a dominant trait and that secret-door-searching is recessive. There will be pregenerated half-breeds soon.
OH! FORGOT TO MENTION SOMETHING! Half-breeds of the Planeborn are called Planetouched X (Planetouched elf, planetouched dwarf, etc), and half-breeds of Deathborn are Deathtouched just as Dragonborn half-breeds are Dragontouched. Did you see wat I did thar?
