Demons

[1darklord]

Hey Guys,

I know the game is mostly random in where you can buy troops but I've completed Sheterra and not found any Archdemons or Executioners for sale. Is there anywhere else in the game that will usually sell higher level demons or have I lucked out?

Archdemons are less of an issue as I got a stack from a Summon Colossus Scroll, but I would like to be able reinforce them.

Also can Executioners be upgraded from Demons? If so that may be something I should consider.

Cheers,

Daniel.
