Night Lies - The False Barracks and Captain Qerth
Taking out their fake barracks is quite easy...conceptually. The battle is an absolute nightmare on hard, and incredibly easy on normal. I’ll cover that in a second though. The battle with the bandits takes place entirely in the main room of the mansion. Archers will try to hold the steps while the fighters will flood the floor.
Captain Qerth is a brutal enemy. He will do a buff fairly often that greatly heals the men on the floor. He can also do a version of the pommel strike, in which he’ll punch one of your men after setting down his sword. This stuns them for a while and leaves them badly hurt. Don’t let anyone engage the captain with low health. Finally, he has a whirlwind ability that does a lot of damage. If you see the yellow light start spinning, fall back until it passes (except for your tank, they can usually ignore it).
Qerth can be very tough, because you have to kill him quickly. There are several waves of reinforcements that come in regardless, but it appears that additional waves will just keep coming as long as Qerth is alive, with smaller numbers of ridiculously elite guards. If you don’t kill Captain Qerth after a few waves, it may be difficult or nigh impossible to hold out after the long battle.
You’ll want to have a rogue with you, along with a tank and a warrior. You’ll probably need Anders as a healer, since having the extra health option is vital. Buy some health potions before you engage too. They’ll help a lot.
The key seems to be a lightning raid on Qerth. Qerth can be frozen and stunned by several spells. While in this state, backstabs and mighty blows will do tremendous damage. If you can keep him off balance you may be able to kill him very quickly while your tank ties up the rest of the men. Note that Qerth will chug health potions if given the chance, so don’t let up for long.
Once Qerth dies, the battle is easy. You just have to circle up in the center of the room and hold out for another wave or two until the guards die. Loot the bodies and loot the chest in back, then leave.
Note, that if you just can’t do this, lower the difficulty. On normal, Qerth will die in a matter of moments under a good barrage. He won’t heal himself nearly as much and the battle becomes very easy. Temporarily lowering the difficulty does wonders for frustration.
