With Campaign Fiesta currently active, I'm working on taking over the Northlands for the Allied Nations. The quickest way to do that is to kill the campaign beastmen outside of campaign battles, rapidly increasing influence and preventing the allied NPCs from getting overrun when the battles are active.
I've managed to get Castle Zvahl Keep (S) to 65%, Castle Zvahl Baileys (S) to 100%, and Beaucedine (S) to 90% since yesterday. Bastok currently holds Xarcabard (S), but the beastmen have basically overrun it. The goal is to cap Allied influence in Keep (S) and Beaucedine (S) today, then focus on Xarcabard (S) until tally, topping off the other three zones as needed.
Right now, it's just my two characters bouncing between zones. If anyone else wanted to also camp Xarcabard (S), that'd be a huge help in unlocking Fiat Lux by next campaign tally this Sunday. While I'm San d'Orian, players signed up with Windurst or Bastok can still take part in Fiat Lux provided they have a Medal of Altana §§§§ and their nation controls at least 4 outdoor zones.
I also managed to get La Vaule (S) from 0% to 25% in a single murder spree, but unlocking Splitting Heirs is a secondary objective at this point (although it does have a chance to drop Heavy Metal Plates and Riftcinders during the campaign).
