- For that, you need to have one player being attacked and all the others attacking or supporting the attacker.
- The Reach is chosen as the attack area because it's the territory with the most adjacent areas and especially land areas (a land area is better than a sea area because you can pack more combat strength in it).
- You have 7 territories to fill for the attackers, and 24 barrels on the map. So you can have at most 4 armies of 4 and 3 armies of 3 (2 players will have 2 attacking armies).
- So you can have 10 SE and 15 knights attacking, which makes a fighting strength of 70.
- you can have 4 S* on the map and 1 M*, so that's 5 more.
- the highest card is Stannis so that's 5 more. (Kevan and victarion aren't as good, because for every 1 combat strength, you have to sacrifice a KN for a ship or a footman, so you lose 1 combat stregth).µ
All in all, that makes 80.
Is it possible to achieve more ? Is it possible to recruit all these troops, move them in position around the reach and get the necessary barrels at the same time, all that in only 10 turns ?
