Gameplay tactics on the S map.

And in which castle, besides Titan and Necromancer, do you focus your army on level 1?

You probably didn't understand me; I mean not level 1 creatures, but the hero. I'll try to write more clearly in the future.))
You suggest taking a hero with an archer skill; are there any other suggestions for a hero with a ballista or swiftness skill? Are there any other options for a hero who specializes in level 1 creatures (Galtan, Ignat, etc.)? Who is better? Why?
