I've been wondering for a while about strategies that might be used to make the impact of a small amount of people have a large impact in campaign. So far my strategy involves heavy abuse of SCNMs and camping in the strongholds using a large amount of blms to use -ja spells and possibly meteor with another group to take care of the nms. This really is all effected though by how much SCNMs lower the enemy stats and raise ours. Ideally a couple small groups could get things to the point where the allied NPCs can regularly win the normal battles without our help.
