⚠️ The dragon is missing here. If you copy the values from each character's stats page, the dragon's share is left out and your army comes out too small. Safer: read the values straight from the attack selection screen – there the game has already added up hero, captains and dragon. Then the setting “1” is all you need.
The automatic mode looks for the largest base count that fits inside your leadership, authority and dominance. Some capacity may stay unused because of the stack ratios. The output uses base values; personal combat bonuses and Fenrir XP are not simulated.
