Kenku (5e Race Variant)
From D&D Wiki
Not all kenku rely solely on the nonviolent aspects of thievery and such. Many become assassins and other bloody workers of the underhanded sort who stealthy kill and lie about it right under their beaks. They are the ones you should fear, for they are mixed among the normal forgers and cowardly squealers.
This race variant replaces the expert forgery and kenku training traits. You gain the ambusher and voice of deceit traits.
Voice of Deceit. You are proficient in the Deception skill.
