How to get a Daemon army as soon as possible?

[Autoclave]

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?

[Metathron]

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.

[Metathron]

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.
