He's still much weaker as a mortal in Oblivion than as a mortal in Daggerfall...maybe part of his power was drawn off of him in the creation of a divine King of Worms during the Warp in the West?
As old as this quote is, as a person who has actually played Daggerfall, I feel the need to point out that the King of Worm's level of personal combat power is
totally unknown in Daggerfall. Certainly, it is implied that he has influence everywhere, enough to, in terms of game mechanics, give the PC a whopping +100 in reputation points should he hand the Totem and Mantella over to the King of Worms. But this, and personal ass-kicking abilities, are two completely different things. The only thing we ever see is a red robe concealing a face in shadow, with glowing eyes peering from under the hood. And zombie messengers.
TRAVEN killed Mannimarco in Oblivion. If you think you did, then you're just as deluded as the mages of the guild that hold your character to be Traven's successor.
OK, so maybe Traven had some help, but the point is, Mannimarco is NOT a pushover without Traven's soul with you.
Is it even possible to face him before this quest line opens the fight up? But yes, I agree that without Traven's help, the KoW "would" be much scarier.
That's interesting. Could it be that what the Jills did was to sever his connection with 'his' moon in some way and that in Oblivion he was attempting to reinstate that connnection?
Gotta feel sorry fo rthe guy - every time he is ready to strut his stuff he meets up with 'the player'.
Actually, Oblivion is the only time the King of Worms fought "The Player." In Daggerfall, "The Player" was instrumental to his plans... indeed, The Player actually handed over the Mantella, in one of the possibilities that composed the metaevent we call the Warp.
