Eberron Changelings for Pathfinder

In the Eberron setting, changelings are a shapeshifting race descended from doppelgangers. They were converted to D&D Fifth Edition in one of the very first columns in the current "Unearthed Arcana" series, which prompted me to try converting them to Pathfinder. Because Pathfinder already has a "changeling" race (descended from hags), I have renamed them half-doppelgangers here.

I have translated the race's traits given in the Eberron Campaign Setting book (for v.3.5) using the Race Builder rules in the Pathfinder RPG Advanced Race Guide. Traits marked with an asterisk (*) are not standard traits from Chapter 4, but have been priced compared to similar abilities.

My wife Erika has helped me create a sample 1st-level half-doppelganger stat block much like those presented in the Bestiary and Monster Codex.
