Chapter 24: March on Sojourn
Objective: Open the Gate
To open the gate, you will need to fight your way to the top of the southern wall and use one of the cranks. This stage is almost entirely physical fighters, but there are a few mages tossed in to keep it from being completely one sided. There are a few archers and some champions that have higher attack than others, so be careful to take out the most dangerous ones first.
You should be able to use the walls and tight corridors to form bottlenecks. In particular the foes on the right wall can be picked off with a high defense ranged unit (or a sniper with range 3 attack), without exposing your other forces to attack. The archers on the south wall can also be baited into moving up to attack a high defense unit & then countered with a sniper.
