20/20 collector fire staff

Does it exist and if not is there a weapons merchant one?

thanks in advance

You can trade 5 Massive Jawbones with Karl Jacobs for a 20/20 max Fire Staff.

Have a look at this post for more details. He's at the point marked i.

much appreciated

There's also a trader in Droknars I believe who will give you a 20/20 fire staff for 5 Icy Hearts (from Ice Imps).
