I'm not sure if I'm just not getting the trick - that was the case with many other special battles... However, I'm really not getting the one where you have to get 3 gold wagons within 3 rounds (from the bandits near the monastery). Any tips?
Okay, so there are two goals in the battle - the first is destroy three of the escaping gold wagons. The second is win the round with a higher point total as usual.
I waited to the very end of the chapter to do this fight as I found it very difficult. By then I had Meve: Rivian Broadsword, Eyck of Denesle, Maticore Trophy, Fake Floren, Lyrian Arbalest + and other good cards that I didn't have when I first came across the battle.
I led by placing the Manticore Trophy
The first gold wagon to come out was hit by the Manticore Trophy, then meve: rivian broadsword. Then I planted a War Wagon I believe I attacked again with a arbalest +, but don't remember. This wagon escaped.
I recalled The war wagon with a decoy and replanted it to get more Light infantry. They help for making arbalest stronger and when destroyed inflict 5 damage to a random enemy.
The first gold wagon i destroyed was instantly taken out by a powered up Eyck of Denesle The second to go by a combination of Meven and arbalest. The final by arbalest.
I have a lot of arbalest + in my deck and regiment drummers. When the final wagon came out the regiment drummers had all performed their order so I played Reynard Odo, which was one of my last cards, hoping to draw more arbalest from the regiment drummers renewed orders. The Manticore Trophy helps out a ton as every card the opponet plays get damaged when it comes out, even if only by a little, it also helps Eyck power up fast which will guarantee he can kill a gold wagon at some point.
Hope all that helps with some strategy!
