I never noticed this in all the play throughs I've done: When Elmo uses the radiant ranseur, he sobers up! Is this a Co8 thing? I love it! I am playing 8.1.0 NC.
When he joins you have the option of him sobering up. Was he drunk before he equipped it? If he was, this is a really cool feature.
Yes, he was drunk before he equipped the ranseur. In fact, if he unequips it, he goes back to being drunk.
