Favored (of the X) gets a piddly +2 to a specific skill.
And then wtf nobody knows extra goodies.
Only really useful for "That Feat In Cityscape"
to get the +1 rank, for early entry into PrCs.
One of the few ways get by a Skill Ranks prereq.
Warforged + Intelligent Item + PAO + Fusion
... or Dusk Giant ; being the others.
