In the heat of battle, they will betray the Warchief and kill him. To do this, you need to recruit Captains to your army and have them infiltrate a Warchief’s squad. Taking them out will make your job infinitely easier. Take out the Warchiefs. These Warhiefs are key Orc military members who stand on the ramparts, and they are extremely strong.If it is equal to or lower than (recommended) your assault level, read on. Each Fortress has a defense level- if this level is higher than your assault level, don’t bother taking it on yet and come back when you are better prepared. Fortresses are gigantic castles and outposts.Instead, let’s talk about the smart way to do things.
You could realistically just try doing this all by yourself- which would be freakishly difficult and unrewarding. But these are really hard to actually capture- your army needs to scale the walls, claim each victory point while fighting off the orcs that try to intercept you, make your way to the Overlord’s room, and defeat them while they have a swarm of backup orcs trying to intercept you, before you can take one for yourself. These are giant outposts that you storm and take on in the game.
