Question first:
I've checked on Search but can find nothing about Wynn, who is writhing on the ground close to the real Emissary.
Talk got nothing, Examine got that his humanity had gone and he was just a weapon for the Shadow Priest. Ok.
There was no option that I could find to kill him, and he was healthy so no healing needed. But it was horrible to just walk away and leave him there. Is there ANY way you can do anything for him? Or are you stuck with leaving him there writhing and twitching?
Comment: The False Emissary in Bonegnasher is VERY useful if you are careful to not threaten him, but insist on him accompanying you. He comes along quite happily and is VERY useful in Eyegouger. In fact, with him, Grobnar and Casavir (to say nothing of Khelgar and my own char, who is a Rogue), the team is seriously overpowered. Of course you have to kill him at the end of Eyegouger's cave, but since he is quite delicate, it's not difficult - especially if you didn't stop to heal and refuel spells after the last fight. Buit I'm gonna miss all that firepower.
