The Arks of Omen Grand Tournament Mission Pack arrives with updated missions, new secondary objectives, and major changes to how you’ll muster and deploy your forces. The biggest changes centre around the new Arks of Omen Detachment, which gives you unprecedented flexibility when building your army. This Detachment is incredibly flexible and will work for all factions, though there will be a couple of specific additional rules to it to allow for unusual armies like Drukhari and Dark Angels forces.
