Archibald, mission 7.

Now a question:

How do you complete the seventh mission as Archibald? :-D

2 options
1. On foot. Generate a Barbarian in the tavern who quickly levels up logistics and pathfinding, gather ogres (preferably generated upgraded ones) around the Castle and march. Minimum - 6 days
2. Using DD. Generate a sage in the tavern; the yellow player has DD at level five in their Castle. Gather ogres, capture the yellow Castle, build magic and jump. Minimum - 5 days
You could also generate DD in the pyramid, but I couldn't find a hero who would level up navigation, expert wisdom, and pathfinding, while still getting knowledge.
