The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
I have to go with changelings. At-will shapeshifting is awesome, and the ability to choose between Dex and Int for their second +2 (they all get a +2 Cha) opens up many more class options for them.
Synopsis: The lone creature to emerge from the secluded area where the two held their mortal combat, a half-elf is seen walking out. Who then proceeds to shapeshift back into his natural form. Suckers!
Give me half-elves that are marginalized by both societies. Changelings are kinda cool, if kept rare, though. This one is actually a vote I had to think about -- maybe the only one in this entire round -- but I'm going with Elrond.
