How to get a Daemon army as soon as possible?
 

I really like Executioners. And I want to have them as soon as possible.

Is there any way besides going to sheterra or summon them using demonologists?

What is the shortest way to get to shetterra?

The shortest is to kite (=steal navigational maps) your way there. The Shettera map is guaranteed on Tekron, Elon and Nameless Island and there's a 50% chance it might pop up on Montero as well. I usually get mine on Elon.

verona->umkas->nameless-> shettera/ My usual way. Umkas map on verona easy kiteable, Nameless map on umkas also one of the easiest, shettera map on nameless unguarded at all.

Umkas? Eugh, hate that island and hate kiting there, the paths are way narrow.

You have like a 66% chance of finding an unguarded Shattera map in Montero underground.
