Seems like another ancient one right up there with Atlach that's impossible to beat with a low number of investigators, and even with a high number I don't see it.
Realistically you can hope for +6 combat per hand. Let's give our hopes up even more and say that every investigator has a base 6 fight. Let's go even more out there and say that not only does every base 6 fight investigator have a +6 weapon per hand, but that they have both a physical AND magical version of each. If you manage to get these AND go into final battle with everyone blessed, THEN you could pull it off.
But good lord how is that supposed to happen? And this is without the epic battle deck (new house rule: no epic battle deck until we've beat an ancient one without them). How on earth did people beat him? Clue-stuffed shotgun Joe?

Which is why those older Ancient Ones need "upgrades". I'd like them to be official game sheets, but, scattered about, I've read several "advanced" versions of each of them that work, like Mask-Spawning Nyarl. A serpent-y expansion for Yig would be great too.
