I don't have my 1E material anymore - anyone know if Raging was an ability for either the Conan writeup or 1E Barbarian? If so, all Conan had to do was rage once in the source material, and Gygax would see that as justification for the ability.
No, no rage in 1e Unearthed Arcana, I'm not even sure when it popped up, maybe 3e ?
