Heart of the Night

even if the troop stats aren't ideal, phantom archers can do a lot, and there's no need to summon elementals.

Also, the first Necromancer is generally the most challenging battle on the map.

I also thought that in the situation with the ship, you don't have to cheat or jump around if there's no monolith – the Marauder could have allowed you to complete it fairly, but you would have had to know in advance that it was needed.
