Mission

A mission and a combat are the same thing: a tactical fight played out on a grid of squares.

Enemy force

The enemy force is drawn from cards at the start of the mission. Each monster faction has a deck of available monsters, that starts with two basic monster types and increases as calamities occur. Each card drawn normally adds one of that type of monster to the battle, except as the campaign progresses some cards will be upgraded to "Monster II" and "Monster III". These add 2 or 3 of the indicated monster, respectively.

The base number of cards drawn depends on the mission type. It starts at 3 for Assault Site missions. If the territory is Infested, add 1 card, +1 for each contiguous territory infested by the same monster faction. Then add 1 for each full chapter you have completed in the current campaign (ie, if you're in Chapter 3, add 2).

Assault

The most common type of mission is started by choosing the Assault job on the overland map to destroy an enemy force occupying at territory. Victory removes the enemy force from the map.

Defense

A battle that begins whenever an enemy army moves into a territory occupied by one or more heroes. A Defend against incursion event is triggered, and then a battle automatically begins in which the heroes goal is to survive for a set number of turns. Various bonuses can be had during the battle if the heroes have completed Prepare Defense jobs ahead of time. Victory removes the enemy force from the map.
