Demonsbane..

I just got the the King Raitwall's Tomb and I beat the optional first Demon Wall and the one you have to fight. It mentioned something in the guide about a secret treasure, that "may" contain the Demonsbane sword. But I have no luck finding it.

It is even worth it at this point?

Could be.

(SPOILER)
You have to beat both walls, then examine where the optional one was... a path opens.. it leads to one chamber. In that chamber.... something... might..... spawn... :)

I beat both walls, and when i examined the stone the paths on the side opened up so i could cross them, is that where it is?

EDIT : If the treasure isn't there do i need to reset, or just keep entering and exiting?

You can save at the entrace(take the waypoint thing out) and then come back... travel to the place the chest is(its along the path).. if its what you want.... get out and save.. if not.. start then square.

Does it matter if you take the left or right path?
And do you need to follow the path all the way down to the chamber, or will it appear on the path on the way down there?

Either path will do.

They both connect, and at a certain point on that path(in the room with monsters)... a chest appears, the chest appears decently often.... the sword is uncommon.

It is worth it. The first demon wall is insanely hard, but the Demonsbane is one hell of a good weapon for a while.

Ty all.

I just got it last night.
