I only see one Beorning skill that is described as a "Cry" exactly. But the name of many skills has the word "Roar" in it. Are they all affected by the Roar Damage Tracery? Or just the ones that have the type Cry?
If I recall correctly the Roar Damage tracery effects Vigilant Roar, Thunderous Roar, Piercing Roar, and maybe even the knockdown from the yellow tree before you trait away the damage in exchange for extra range. There could be more but overall its a very small selection of skills.
