Accept "A Plague Upon thee" and "Mission Accomplished!" turn in Mission Accomplished at the bulwark.

Get a drink and a snack, this is a really, really long circuit.

Right-click the charm half you got to combine it with the first, then turn it in to the ghost lady in the house to complete the quest chain.

Click the barrel to turn in the quest, click it again to get the follow up.

This camp is really close-knit, so you'll need to be extra careful on your pulls to make sure you don't get too many at once.

Once you finish Unfinished Business, turn it in, get the follow up and move on.

Cavalier Durgen spawns and wanders around the tower. Kill him and then travel to the top of the tower to get the Mark of the Lightbringer out of the holy coffer. Turn it in, skip the follow up, then move on.

You do not have to stand in the doorway(which aggros the elite) but you have to be pretty close to the entryway when you click the torch. But don't worry, just keep inching forward and trying it until it works and you won't aggro the elite.

AGain, be careful.

Turn in "A Strange Historian", accept "The Annals of Darrowshire" and "A Matter of Time"

You need to be close to a silo, then blow the horn in your inventory. A worm will spawn, which you kill. When it's dead, there's a possibility another will spawn. And possibly another from that, and so on. What's worse is that sometimes more than one(i've had up to 5) will spawn at the initial horn blow. They're pretty easy, but make sure you're at full health/mana before each blow of your horn. They also cast Slow on you, druids can shapeshift out of this(but it's not reccomended since it kills your mana) but for everyone else you're pretty much boned.

It's not hard to avoid the packs of mobs around it, just sneak along the walls and you'll be fine. Anyhow, once inside you'll se a lot of books scattered on the ground. The one you need has a light, non-tinted top half, while all the "wrong" books have a dark top half. It's hard to tell and honestly you probably won't figure out what I mean until you actually get the book, by which point you've probably spawned dozens of guardians. Two of them spawn when you pick the wrong book. Either way, get it and return to Chromie. Start Circuit 3, there's too many dots!
