How about a feat for all the players who want to splash in another race?
You have a mixture of heritage in your family. Choose a race you are not a member or and do not count as. You gain the following benefits:
- Gain a +1 bonus to one of the attributes that race normally gains a bonus to, to a maximum of 20.
- You not count as a member of that race for any feats, abilities, and class abilities. You gain any benefits and penalties that those feat and abilities would cause.
